Sanctum Door
The Sanctum Door is the entrance into the main hall of the Seat of the Primus, located at the top of the Bleak Redoubt in Maldraxxus.[50.4, 68] It is initially sealed shut, but over the course of the Maldraxxus storyline, players gradually empower each of the door's five runes with the Blade of the Primus before finally opening it during 
[53-60] The Door to the Unknown. It remains permanently open for players who join the Necrolord Covenant.
