To a surface dweller, he might have passed undetected only a foot away. The padded footfalls of his lizard mount were too light to be heard, and the pliable and perfectly crafted mesh armor that both rider and mount wore bent and creased with their movements as well as if the suits had grown over their skin.

Dinin’s lizard trotted along in an easy but swift gait, floating over the broken floor, up the walls, and even across the long tunnel’s ceiling. Subterranean lizards, with their sticky and soft three-toed feet, were preferred mounts for just this ability to scale stone as easily as a spider. Crossing hard ground left no damning tracks in the lighted surface world, but nearly all of the creatures of the Underdark possessed infravision, the ability to see in the infrared spectrum. Footfalls left heat residue that could easily be tracked if they followed a predictable course along a corridor’s floor.

Dinin clamped tight to his saddle as the lizard plodded along a stretch of the ceiling, then sprang out in a twisting descent to a point farther along the wall. Dinin did not want to be tracked.

He had no light to guide him, but he needed none. He was a dark elf, a drow, an ebony skinned cousin of those sylvan folk who danced under the stars on the world’s surface. To Dinin’s superior eyes, which translated subtle variations of heat into vivid and colorful images, the Underdark was far from a lightless place. Colors all across the spectrum swirled before him in the stone of the walls and the floor, heated by some distant fissure or hot stream. The heat of living things was the most distinctive, letting the dark elf view his enemies in details as intricate as any surface dweller would find in brilliant daylight.
