Cloister Wraith
The Cloister Wraiths were creatures found in the Cloisters of Gallifrey which was a crypt beneath the Capital. They were representations of dead Time Lords whose minds were uploaded into the Matrix and were designed to guard the Matrix. When anyway dared to enter the Cloisters, the Wraiths would trap them forever within.
