Ish Sah

From MTG Salvation Wiki

Ish Sah, the Vault of Whispers, was the dwelling place of Geth on Mirrodin, as well as other Moriok and necromancers. It is shaped as a cone-like mountain with a circular hole towards the middle, and an opening at the top which spews necrogen mist. Geth controlled the nim from here, though it also was a place of study for the dark arts and a lodge for Moriok artificers. Those who stayed here were known as Disciples.
