The Great Gate Sigil Stone

A Sigilium Sanguis housing a Great Sigil Stone within a Great Gate.

The Sigilium Sanguis are rooms located at the top of the main towers of Mehrunes Dagon's planes of Oblivion. Their primary use is to keep the Sigil Stones that maintain the portals between Oblivion and Mundus. Removal of the Sigil Stone at the center of the room will cause that portal to close permanently.


  • If translated from Latin to English, "Sigilium Sanguis" can be translated literally as "Blood Seal."
