The corridor entered some sort of gallery ahead, which seemed to bulge in both directions. In that I could not sec what lay at either hand beyond a certain point, I knew that I would have to expend another spell sooner than I might wish. I spoke the word for my invisibility spell, and the world grew several shades darker. I had been hoping to get a little farther before I had to use it, since it was only good for about twenty minutes and I had no idea where my prize might lie. But I couldn’t afford to take chances. I hurried along and passed into the gallery, which proved empty.
I teamed a little more geography in that place, though. I had a view from there into the next courtyard, and it was gigantic. It contained the massive structure I had glimpsed from the other side. It was a huge, solidly built fortress; it appeared to have only one entrance, and that well guarded. From the opposite side of the gallery, I saw that there was also an outer courtyard, leading up to high, well-fortified walls.
I departed the gallery and sought a flight of stairs, almost certain that that hulking gray-stone structure was the place I should be searching. It had an aura of magic about it that I could feel down to my toes.
I jogged along the hallway, took a turn and saw a guard at the head of a stairway. (f he felt anything of my passage it was only the breeze stirred by my cloak. I rushed down the stairs. There was an adit at its foot, leading to another corridor-a dark one-off to the left; and there was a heavy ironbound door directly before me, in the wall facing the inner courtyard.
I pushed the door open, passed through and stepped aside quickly, for a guard had turned, stared and was beginning to approach. I avoided him and moved toward the citadel. A focus of powers, Luke had said. Yes. I could feel this more strongly the closer I got to the place. I did not have time to try to figure out how to deal with them, to channel them. Anyway, I’d brought along my private stock.
When I neared the wall I cut to the left. A quick circuit was in order, for informational purposes. Partway around it, I saw that my guess that there was only one apparent entrance was correct. Also, there were no windows in its walls lower than about thirty feet. There was a high, spiked metal fence about the place, and a pit on the inside of the fence. The thing that most surprised me was not a feature of the structure, however. On its far side, near the wall, were two more of the large broken kites and three relatively intact ones. The matter of context no longer clouded my perception-not with the unbroken ones before me. They were hang gliders. I was eager to take a closer look at them, but time was running on my invisibility and I couldn’t afford the detour. I hurried the rest of the way around and studied the gate.
The gate to the fence was closed and Banked by two guards. Several paces beyond it was a removable wooden bridge, reinforced with metal strapping, in place across the ditch. There were large eye bolts at its comers, and there was a winch built into the wall above the gate; the winch bore four chains terminating in hooks. I wondered how heavy the bridge was. The door to the citadel was recessed about three feet into the stone wall, and it was high, wide and plated, looking as if it could withstand a battering ram’s pounding for a good long while.
I approached the gate to the fence and studied it. No lock on it-just a simple hand-operated latching mechanism. I could open it, run through, dash across the span and be at the big door before the guards had any idea as to what might be going on. On the other hand, considering the nature of the place, they might well have had some instruction as to the possibility of an unnatural attack. If so, it would not be necessary for them to see me if they responded quickly and cornered me in the alcove. And I’d a feeling the heavy door inside was not unlocked.
