Once I cleared my papers and booked passage on one of the riverboats, I found a hotel room for the night. I was tempted to think of the place as primitive or backward, since we were so far from what I had come to think of as civilization, but Dembut had every convenience you could ask for. Up-links to the whole Hormling data mass, entertainment parlors that were 4D capable, clean VR stalls, good restaurants. The Dirijhi don’t like big power matrices, so everything on Ajhevan runs on portable fusion generators; cold boxes, they’re called, and for a village the size of Dembut, about a dozen were required to power the town. Hormling technology, like nearly everything that works in the Cluster. This and much other interesting information was piped to the screen in my hotel room, the loop playing as I keyed the door and entered. I muted the sound and threw my bag onto the little bed.
I bought a girl for the night. Her name was Tira and she had a brother who was a symbiont, too. Ajhevanoi are pretty free sexually, and prostitution is considered a nice way to make some extra money, especially in a tourist town, as Dembut is, so there are a lot of people registered with the agencies. People in Ajhevan are not usually hung up about lesbians, though now and then you still get a feeling that they don’t know altogether what to make of us in the smaller towns, so I was apprehensive. Tira was a free spirit, though, and we had a nice dinner and went to the room and she gave me a massage and I returned the favor and then we wrapped round each other and got serious for a while. She had no problem with lesbians, clearly, and I felt worlds better when we were done. We talked about our brothers and I asked if she had seen hers since he made the change. She saw him often, she said to be near him, she had taken up her trade in Dembut – her trade being rune-reading for tourists in the market, the sex was a sideline. She liked the forest, she liked her brother, she liked the difference since he underwent the change, she had thought about becoming a sym herself. “Beats having to work for a living,” she said.
In the morning, I met the riverboat on time and waited impatiently to be underway. Today the river station was staffed by two different syms, one who had been a man and the other who had been a woman. The bioengineering that gets done on a symbiont starts with neutering, but sometimes you could tell which had been which. The eyes, though, were so difficult to read. I kept trying to place them in Binam’s face.
We got underway in the eighth marking. My fellow passengers were tourists, a family from Feidre and two couples from New Charnos, southerners, all of them. They were curious about Ajhevan, so I answered their questions politely, while the pilot was busy. I was born here and grew up here, first on a group farm and then in a girls’ commune. After my parents sold my brother to the sym recruiters, I petitioned the Magistrate’s Court for a separation and was granted it, and lived in the commune after that. To be fair, which I don’t always like to be, that’s my way of looking at what happened. My parents didn’t exactly sell my brother, at least, not against his will. Binam had been begging to join the symbionts since he was eight years old and got lost in Greenwood; and my parents were swayed by the bounty and by what Binam wanted, so fervently, and gave permission. I never forgave them for allowing him to make that choice himself, so young, only twelve. Especially since they were paid enough money to sell the algae farm we worked, that they had come to hate. After I divorced them, they bought a big house in Byutiban, on the southern continent, and both went to work in the Prin administration. We reconciled later, though I never did anything to lift the court decision. By then, even if I had forgiven them for selling Binam, I’d never have understood why they went to work for the Hormling.
My boat penetrated into the canopy along a string of Dirijhi cities, according to the pilot, an Erejhen who gave his name as Kirith, though since he was Erejhen that was not likely to be his real name. He pointed out how to spot a city: the trees grew closer and denser, the undergrowth was more strictly regulated, the appearance was formal. There was even a foliage pattern along the river, shrubs grown and maintained in a certain sequence by the tree through a complex process that only a fully mature Dirijh could undertake before symbionts. Nowadays, the symbionts work under the direction of the trees to cultivate the Shimmering Garden, which is the name the Dirijhi give to Greenwood.
Overhead, in the cities, the trees intertwine upper tier branches in one of seven patterns, sometimes a mix of all seven in a large city, like the capital. In the branches now and then we would see a sym, but only once that whole day did we see one on the ground. One of the couples asked if Kirith knew any of the names of the cities, and he answered that the Dirijhi had no spoken language and the symbionts never attempted to transliterate the speech that passed between sym and host. The only words the syms ever gave us are the name they use for the tree people, “Dirijhi,” coined from a word for tree in one of the old languages of Senal, and the name for the forest, “Shimmering Garden.”
We were headed for the Dirijhi capital, near the center of the forest. There I would transfer to another flatboat that would carry me along one of the water-channels leading west into the interior, where Binam and his tree lived. We were passing tourist boats all morning as they stopped along the shore, places where the Dirijhi had agreed to allow walking tours for a stiff fee. The tour spots changed from time to time to give the riverfront trees a respite. Since the trees migrate toward the closest river or canal over the course of their extremely long lifetimes, the oldest, longest-lived trees end up along the shore and die there; though trees occasionally refuse to make the migration and many die in the interior before getting all the way to the shore. They migrate slowly, by setting roots carefully and deliberately in one direction and shifting themselves by manipulating the compression and tension of wood in the main bole, and can move as much as a full standard unit in about a standard century, about seventy years Aramenian. It takes a person about a half a day to walk that distance; it took the symbionts to tell us the trees could move at all.
The trees along the river nearly hypnotized me. A lot of them were dead and decaying, since they were the oldest; but their gardens were still maintained by syms in the neighboring trees. The living trees give off all kinds of scents, according to Binam’s letters, the patterns changing with the religious and social calendar, and the effect can be ecstatic. We were getting the tourist spray along the Silas, but even that was heavenly. Some of the Dirijh rise as tall as a thirty story building, if you’ve ever seen one of those. They are massive creatures with a central trunk or bole and a series of buttress roots rising to support a huge upper canopy. The central bole becomes massive and the buttress roots rise up as far as the lowest branches. All the branching occurs from the central trunk, and these massive branches sometimes drop additional prop roots to the ground for support, till a single Dirijh can look like a small forest. The trees can climb four hundred stades high even in Aramen’s 5-percent higher-than-standard gravity, where nobody expected to find the tallest trees in the known stars.
Standard years and standard gravities refer to the year and the total gravitic force of Senal, the Mage world. The standard is necessary since there are so many worlds to deal with in the Cluster, all slightly or very different from one another in physical characteristics. I can admit that and still get a little riled that the standard is Senal. Why not a mean year, a mean day, a mean gravity? My parents think that’s a silly argument, that it doesn’t make any difference. That’s no reason to commit acts of sedition, to work for a rebellion, they say. But I disagree.
I moved for a while to the southern continent, to Avitran, after I got through school in the women’s commune. Trained as a gene-splicer in Genetech, working in a clean lab creating one or another of the seventeen hundred legal variants from standard DNA that define the human race as we know it, three hundred years since the Hormling and their partners the Erejhen began to spread through the local stars, and nearly thirty thousand years since the Hormling themselves arrived on Senal, sent there from Earth to find the Mage, as the Qons Quilian claims. I believe the three-h
undred-year proposition, I don’t know about the rest. I know I don’t believe in Earth.

We slept on the boat, while it continued upriver on satellite guidance. Firesprays flying overhead, now and then a bit of the moon peeping through the canopy. Some of the Dirijh fold their leaves at night to bring moonlight down to the Shimmering Garden. Aramen’s tiny moon Kep orbits the planet in a geosynchronous loop and is always in the sky over Ajhevan; sometimes you can see its ghost in the day. The southern continent Byutiban, on the opposite side of the planet, never sees that moon at all, though Aramen has a larger, red moon, Sith, that orbits farther out, and it goes through phases and appears in all parts of Aramen.
Because the boats are wide enough to accommodate even a tall person lying across them, there was plenty of room for us to sleep, and we spread out bedding after we ate our dinner packet. No question of our sleeping ashore; tourists aren’t allowed that option at any price. I had bought a sleeping roll in Dembut, and the guide showed me how to get into it. Fairly comfortable, given the motion of the river. The boat was tight and dry; the Dirijhi wouldn’t have let it run the river if it weren’t. Peaceful to think that the boat would continue on its placid voyage while I dreamed.
Overnight, we passed through one of the Dirijh cities where the channels cross; out in the center at the junction grew a single Dirijh, one of the conifers, gorgeous and nearly symmetrical, rising right up out of the water, its roots immense, earth filtered out of the river clinging to them, glistening in the moonlight. We sailed around it. The guide woke me up to see; he had understood my interest, knew my brother was a sym. It never hurts for a guide to know a sym, or a relative of one.
“You ever see anything like that?” Kirith asked.
“No. We used to come to Greenwood when I was a kid, but never this far north.”
“You grew up here?”
“Yes.”
“You like it?”
I laughed. “Yes. Very much.”
He nodded. Handsome, like most of the Erejhen I’ve met. He was one of the dark-skinned ones, colored like coffee, with deep, dark eyes. “This reminds me of home, this place.”
“Where?”
“Irion,” he said, “near the forest where the Mage comes from.”
I laughed. “No, really. Where do you come from?”
He tilted his head. “You don’t believe me?”
“I don’t believe you come from Irion. All you Erejhen say you come from there, but most of you were born here, just like me.”
His jaw set in a line. “I come from there,” he said, and he turned away, offended.
All day the next day, we traveled north. This was summer in the northern hemisphere, very hot in most places, but we were perfectly cool, riding along the water in the deep shade. We came to the Dirijh capital, and I got off the boat onto a floating platform and hired a space in a channel-boat going east. Not a single word from Kirith after our conversation the night before. Maybe he was from Irion, but it’s true they all claim to come from there, you have to ask. I’m not a follower of the Irion cult, I know as much as I need to about the place; the Prin are trained there, which is reason enough for me to distrust the rest of the Erejhen, too.
The channel-boat was ready to leave, mine was the last space to be sold, and we were underway as soon as I showed my papers, which were actual physical documents, fairly stained and tired by that time. I got a look at the trees of the central city, which is probably the better way to describe the way this city functions than to call it a capital. Greenwood is defined by rivers and channels that divide the forest in a rough grid, sometimes skewed but very clearly organized. The rivers flow north to south and channels flow east-west. The symbionts say the Dirijhi grew that way deliberately, creating the watershed to make the water run where they wanted, first defining the rivers and then dividing for the channels. The grid functioned as irrigation and fire protection for Greenwood long before it served as a highway for trade, tourists, and sym business. The central city lay at the junction of the Silas, the central river, and the central channel, which the guides have named the Isar, after a river in Irion.
A day and a half east, I got off at the junction of the Isar Channel with the River Os. From there, I would travel inland by truss. The syms have domesticated some of the animal species, including the truss, an oversized bird that has only vestigial wings but has thighs powerful enough to carry two people, in baskets slung over the truss’s back, one on each side. In my case, in the other basket was the sym who owned the truss. The ride was indescribable, I thought I would break bones with all the jolting and bouncing around, but the bird could move. Leaves slapped at my forehead as we headed out of the city into rural Greenwood, the part of the forest nobody sees unless she knows a sym.
Binam’s tree was a youngster and lived pretty far out. All of Greenwood is cut through with creeks and canals to bring water into the interior, and we could have navigated on those except the Dirijhi don’t like the waters to be disturbed so close to their roots. The brain case is in the root crown, where it developed out of specialized root tissue that provided the trees with gravity perception. The older trees along the main watercourses can take the commotion of the boats, because they have to, but everybody travels by truss or by foot in the interior.
My companion in the balancing basket was another kind of guide, hired to lead people like me to the proper tree. Those guides are all syms, who charge a high price for time away from the host. Binam had arranged the guide and the truss, since there was no way for me to do it. The sym kept quiet on the trip, to conserve energy. With this one, I couldn’t tell whether the original had been a man or a woman, and that made me uncomfortable. I watched the undergrowth, smelled the most amazing perfumes, caught flashes of sunlight overhead.
The change in the Shimmering Garden as we left the cities was marked. Different shrubs grew, and vines climbed some of the trees and then cascaded from tree to tree, spectacular festoons of flowers hanging down from the boughs. The truss paths were moss or something that looked like clover, and along either side of the path were flowering bushes, low growing trees, and other kinds of growth that the Dirijhi encourage. No more sense of formality; each tree tended its garden as it wished, and some of them were wildly overgrown, the central trunks nearly hidden behind green walls, screened overhead by the low-growing canopy where it was impossible to distinguish one tree from another. No one can travel safely here without a guide, though the occasional renegade or stray tourist has tried. Many of the plants are toxic to humans, and some of the poisons kill by contact; the truss paths avoid those, but most people on their own wouldn’t know the difference before they were dead.
The truss had a musty smell, but no bugs I could see. Their owners keep them clean, no easy task with a bird. Dun-colored feathers. A mottled pattern of brown and dull green feathers on the back of the neck, that I grew to know far better than I wished.
We traveled through the night, and I even dozed occasionally, my head collapsed onto the woven carry-all strap, truss feathers tickling my nose. We were only allowed to stop at certain oases, mostly in public meadows that the Dirijhi cultivate to open up the canopy to the sky. A place where a Dirijh dies is left fallow for a long time, while the body decomposes, and we stopped at one of those as well. I was glad we were passing through the open spaces at night, since the Aramenian sun can be murder that time of year in the north; in fact, I hadn’t dressed quite warmly enough for the night, and the rest of my clothes were bouncing up and down in the luggage tied to the truss’s back.
I had learned so much from Binam’s letters, nothing I saw seemed entirely foreign to me. He wrote me often in the early years when he was working as a guide, when he was fascinated by what he was learning, by the trees he was meeting, by everything in Greenwood. I was fascinated too, once I was living in the girls’ compound and studying genome manipulation, safely out of reach of my parents and the sym recruiters.
The notion that my br
other had changed himself from an animal to something that was a hybrid between animal and plant, to read about the changes he had gone through, astonished me. The subject is neutered, put into stasis, immune system completely disabled. The body is then suspended in a high-protein bath and infected with a first-stage virus that eventually reaches every cell, attacking the DNA itself, replicating parts of the viral DNA onto the human genome. Changes begin. The digestive system withers, becomes vestigial, and one day is gone. The heart shrinks and the circulatory system withdraws to the musculature and the skeleton; the lungs shrink and split.
At this stage, a second virus is introduced, and this one initiates another series of changes. The protein bath is sweetened with sugars like the ones the trees make. Chloroplasts replace the mitochondria in all the dermal tissues, and the dermal tissues change, the venaceous structure becomes disconnected from the blood supply. A layer of flexible xylem and phloem grows under the new dermis, forming a new circulatory system for water, oxygen, and nutrients. This system is based on the Dirijhi’s own structure, but is more flexible than in the Dirijhi themselves. The skin develops stomata for release of moisture and exhale of gases, and comes to resemble a soft leaf in texture. Part of the lungs are used to compress air for speech and the rest of the lungs become a focus for xylem and phloem tissue. The blood filters through both, receiving nutrients and oxygen for the body’s animal components, the muscles and skeleton, nerves and brain. The body photosynthesizes, but supplements its diet by feeding from the host through the palms, the bottom of the feet, the anus, and the mouth. The sym can slow its heart to a crawl and still function, which it does in the winter if its tree becomes dormant.
