Fortunately, this region of the World Above had many landmarks. They passed a number of mounded hills, each capped by a thick tangle of trees and vines, and chunks of weathered stone half-buried in the ground. T'lar clambered over a fallen obsidian column, carved in the shape of a person with four arms folded across their chest. Whether it was meant to represent male or female, T'lar couldn't tell; there were no obvious genitalia. Moonlight threw the glyph carved into its forehead into shadow. T'lar was no scholar-she couldn't read the glyph itself-but she recognized it as an archaic form of Espruar. She glanced around at the hills and realized they were the ruins of ancient structures. So perversely fertile was the World Above that soil and vegetation had completely hidden the tumbled buildings under a thick, loamy skin.

The wild elf halted before one of the hills and gestured by jerking his head in that direction. One of the trees sprouting from the hill had fallen, leaving a hole in the mound that revealed the masonry beneath. T'lar peered into the hole and saw a glint of metal: an adamantine door. Its hinges had torn free of the crumbling stone, allowing the door to fall inward. Now the metal formed a natural ramp into the darkness at the mound's hollow center.

The wild elf glanced back at her, obviously reluctant to venture into it. T'lar shook her head. She snapped a kick at the back of his legs, knocking him to his knees, and pointed. "Inside."

The wild elf glared at her, but complied. He wormed his way forward on his belly, into the hole. T'lar crouched and followed cautiously, Nafay's dagger in hand. She smelled damp earth, and spider musk. A cobweb brushed her face. But the attack she had anticipated didn't come. Though webs were everywhere, the inside of the ancient building did not contain a spider.
