Avatar of Ydersius
The Diety Ydersius restored but not at his full power
The god has not yet completed his restoration, and has only recovered enough of his strength to manifest an avatar standing 20 feet tall and weighing over 10 tons.
When Savith faced Ydersius at the height of his power on the battlefield, she drove him to this inner sanctum and finally beheaded the snake-god. The geyser-like spray of acidic blood from Ydersius’s decapitated body landed here on the cavern floor, burning through the stone. Ydersius’s headless body retreated into the Darklands through the resulting chasm, as far from Savith’s blade as the god’s burrowing body could take him.
Since that time, the Chasm of Retreat has seen little use. Even the creatures of Orv who find the vertical shaft leading into their realm avoid using it, as the taint of Ydersius’s blood still poisons the very rock. Anyone touching the rock within the chasm is exposed to a weakened version of the god’s toxic blood, which has soaked into the stone (touch—contact; save Fort DC 25; frequency 1/round for 6 rounds; effect 1d2 Dex; cure 1 save). Anyone falling into the chasm with no means to arrest her fall takes 20d6 points of lethal falling damage when she eventually reaches the bottom, over 6,000 feet below. To get back up requires some means of flight or miles of travel through the Darklands to reach Ilmurea once again.
