All of the Blood Rift's elite ultroloths laired on Calaas. The relative height of an ultroloth's fortress along Calaas's side indicated the owner's status within the Blood Rift's hierarchy.

Kexxon the Oinoloth's fortress, the Steel Keep, sat highest of all, perched among the red and black clouds at the very edge of Calaas's caldera. Corpsehaven sat only twenty or so leagues below the Steel Keep and only two or three leagues above the Obsidian Tower of Bubonis.

Inthracis knew that the day would come when he would face a challenge from Bubonis, when he would himself challenge Kexxon. For the hundredth time in the past twelve hours, he wondered if the time had come. The thought of throwing Kexxon's corpse down the Infinite Deep amused him. The Infinite Deep descended to the center of creation, and its rocky sides were so sheer, so unbroken by any shelf or ledge of significance, that when things fell there, they fell forever.

Without warning, darkness descended on the library, darkness so intense that even Inthracis's eyes could not penetrate it, though he could see in virtually all spectra. Sound quieted; the wind seemed to offer its wail as though from a great distance. Inthracis could hear the walls squirming in the darkness. His hearts beat faster.

He was under attack, he realized. But who would dare? Bubonis?

The words to a series of defensive spells rose to the front of Inthracis's mind and he whispered the syllables in rapid succession, all while weaving his fingers through the air in a series of intricate gestures. In the span of three breaths, he was warded with spells that would protect him against mental, magical, and physical attacks.

He slid from his cloak a metal wand that fired a stream of acid upon command. Then he levitated toward the high ceiling and listened.

The walls of Corpsehaven rustled with a wet susurration. Decayed hands reached down from the ceiling to paw his robes, as though seeking reassurance. Their touch gave him a momentary start. He heard nothing save his own soft breathing.
