Ish Sah, the Vault of Whispers, was the dwelling place of Geth on Mirrodin, as well as other Moriok and necromancers. It was once the stronghold of a long-forgotten human warlord. It is shaped as a cone-like mountain with a circular hole towards the middle, and an opening at the top that 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.
It housed the Black Lacuna.
