Only a moment we stared across that scene of amazing activity before our guards were again motioning us onward, across the cavern's floor. Between the aisles of looming mechanisms we marched, whose formless attendants seemed not to heed us as we passed them. Before and around us glided the great turtle-machines with their burdens, the humming of their operation adding to the medley of sounds about us, only the shapeless nebula-creatures being completely silent. And as we marched on I saw in the great cavern's distant walls doors and corridors leading away to other vast brilliant-lit caverns that I could but vaguely glimpse, extending away in every direction, a great, half-seen vista of mighty white-lit spaces reaching away all about us, stupendous, incredible. And as we went on we saw other narrow shafts in the floor like that down which we had come, saw swarms of the nebula-creatures rising from and descending into those shafts by the pegs set in their sides, moving ceaselessly up and down from whatever other vast spaces might lie beneath us in this titanic, honeycombed world. At last we were across the great cavern, had entered the comparative silence of another corridor, and progressed down this until our guards turned us through a doorway in its right wall. We found ourselves in a great hall, or room, smaller by far than any of the vast caverns that honeycombed this world, but unlike them quite silent, and with no humming machines or busy attendants. The great, long hall, perhaps five hundred feet in length, was quite empty except for a low dais at its farther end, toward which our guards conducted us, gliding before and behind us. As we neared it we saw that on each side of the dais was ranged a double file of guards, each armed with the deadly weapon we had seen demonstrated, while upon the dais itself rested ten of the formless nebula-creatures. Of these ten, nine were like all of the others that we had seen, ranged in a single line across the dais. The tenth, however, who rested in a central position in front of the nine, was like the others in form or formlessness alone, being at least five times larger in size than any of the others we had seen, an enormous mass of white flesh resting there on the dais and contemplating us with his strange eye as we were marched down the hall toward him. I divined instantly, by his strange size and prominent position, that he held some place of power above the others of his race. For weird and alien as his appearance was, there yet reached out from him toward us a strong impression of some strange majesty and power embodied in this monstrous mass of flesh, some awe-inspiring dignity that was truly regal, and that transcended all differences of mind or shape.
