The Moon Temple is the new dungeon added in the Moon Temple DLC and is what the Moon Temple DLC is named after. Unlike the Forsaken Tower or the Pyramid of Prophecy, it is essentially a series of arena-like rooms connected by teleporters, only when all of the enemies in the room have been defeated is the player allowed to move on to the next room. The temple itself contains a powerful arifact known as the Orb of Night and is under seige by an army of vampires led by the "Four Magi".
