Arvin swore softly and kicked at a loose stone. It rolled-farther than it should have. Bending down, he discovered a narrow gap, beyond which lay a wider passage. Clearing away the rubble that blocked it, Arvin realized it must be the tunnel the yuan-ti had used to reach the chamber in which they'd laid their eggs. It was too low to crawl through with a backpack on; he'd have to drag the pack behind him. He tied it by a short length of rope to one ankle then lay prone and wormed his way into the tunnel.

The narrow passage wound its way through the collapsed masonry, up and over sharp bits of stone that scraped Arvin's arms and legs and under jutting blocks that he would have banged his head against, had he not been able to see in the dark. Being in yuan-ti form helped. His increased flexibility enabled him to slither around corners a human would have been unable to negotiate.

At one point the tunnel constricted, forcing him to wriggle forward on his belly with arms extended in front of him. Claustrophobia gripped him a moment later when his pack got caught in the narrow section, jerking him to a halt like an anchor. He was trapped! He would lie there, entombed with Varae's victims, until he starved to death. He scraped at the

rope around his ankle with his other foot, trying to free himself from it-then realized what he was doing. If he left the pack behind, he'd lose his chance to settle his score with Sibyl-the abomination who had killed both his best friend and the woman he loved.

"Control," he whispered.

He blinked away the sweat that trickled down into his eyes and licked his lips with a long, forked tongue. The sweat tasted slightly acidic, reminding him that he was in yuan-ti form. The serpent folk had wriggled through that narrow spot to reach their brood chamber, and Arvin should be able to do the same. It was just a matter of freeing his pack.
