The Scarlet Monastery is located in Tirisfal Glades. Revamped in Mists of Pandaria to replace the Graveyard and Cathedral wings of the old Scarlet Monastery, the dungeon now includes a level 90 Heroic mode with three boss encounters. The monastery is one of the strongholds of the Scarlet Crusade, a group of maddened zealots so dedicated to the defeat of all undead that they frequently attack everyone - even the living.
