And the air currents were fabulous. I had a little red sail plane I used to go sky surfing in, every couple of days. It was the good life. I played drums till all hours in a basement spot up the river where the walls sweated almost as much as the customers and the smoke used to wash around the lights like streams of milk. When I was done playing I39。s about the only thing I wouldn39。m good and I39。t admit even to himself that there were some things other people could do better. If you kept beating him at anything you had to be cheating. He started a nasty argument over it one nightcould have gotten seriousbut Gerard and Caine broke it up. G ive Caine that. He took my part that time. Poor guy . . . Hell of a way to go, you know? His throat . . . Well, anyhow, there I was in Texorami, making music and women, winning at cards and jockeying around the sky. Palm trees and nightblooming wallflowers. Lots of good port smellsspices, coffee, tar, saltyou know. Gentlefolk, merchants, and peons the same straights as in most other places. Sailors and assorted travelers passing in and out. Guys like me living around the edges of things. I spent a little over two years in Texorami, happy. Really. Not much contact with the others. Sort of postcard like hellos via the Trumps every now and then, and that was about it. Amber was pretty much off my mind. All this changed one night when I was sitting there with a full house and the guy across from me was trying to make up his mind whether or not I was bluffing. The Jack of Diamonds began talking to me. Yes, that is how it started. I was in a weird frame of mind anyway. I had just finished a couple very hot sets and was still kind of high. A lso, I was physically strung out from a long day39。t know. The Jac k said, Random. Then its face blurred and it said, Help me. I began getting a feel of the personality by then, but it was weak. The whole thing was very weak. T hen the face rearranged itself and I saw that I was right. It was Brand. He looked like hell, and he seemed to be chained or tied to something. Help me, he said again. I39。s the matter? . . . prisoner, he said, and something else that I couldn39。t bring you through, he said. No Trumps, and I am too weak. You will have to e the long way around.... I did not ask him how he was managing it without my Trump. Finding out where he was seemed of first importance. I asked him how I could locate him. Look very closely, he said. Remember every feature. I may only be able to show you once. Come armed, too. . . . Then I saw the landscapeover his shoulder, out a window, over a battlement, I can39。t answering, he wasn39。d say, that made me decide to go it alone and try to rescue him. I dusted off my own Trumps and tried reaching him again. A s you might expect, there was no response. I got a good night39。t know how they would work there, but that wardenthing had been awfully brightand it never hurts to try anything extra y ou can think of. For that matter, I also took a gun. I had a feeling it would be worthless, and I was right. But, like I said, you never know till you try. The only person I said goodbye to was another drummer, because I stopped to give him my set before I left. I knew he39。t know whether you39。s what I meant about gliding it being a bit different. So, I bore to the west till the woods gave way to surface green, which quic kly faded, dispersed, broke to brown, tan, yellow. L ight an d crumbly then, splotched. The price of that was a storm. I rode it out as much as I could, till the lightnings for ked nearby and I feared that the gusts were getting to be too much for the little glider. I toned it dow n fast then, but got more green below as a result. Still, I pulled it out of the storm with a yellow sun firm and bright at my back. After a time, I got it to go desert beneath me again, stark and rolling. Then the sun shrank and strands of cloud whipped past its face, erasing it bit by bit. That was the shortcut that took me farther from Amber than I had been in a long while. No sun then, but the light remained, just as bright but eerie now, directionless. It tricked my eyes, it screwed up perspective. I dropped lower, limiting my range of vision. Soon large rocks came into view, and I fought for the shapes I remembered. Gradually, these occurred. The buc kling, flowing effect was easier to achieve under these conditions, but its production was physically disconcerting. I t made it even more difficult to judge my effectiveness in guiding the glider. I got lower than I thought I was and almost collided with one of the roc ks. Finally, though, the smokes rose and flames danced about as I remembered them conforming to no particular pattern, just emerging here and there from crevasses, holes, cave mouths. Colors began to misbehave as I recalled from my brief view. Then came the actual motion of the rocksdrifting, sailing, like rudderless boats in a place where they wring out rainbows. By then, the air currents had gone crazy. One updraft after another, like fountains, I fought them as best I could, but knew I could not hold things together much longer at that altitude. I rose a considerable distance
