The Sacellum of Virtue is a small dungeon that can be found in Gardens of Hope 2nd and 3rd Tier in Act IV of Diablo III. There is usually a shrine immediately inside, after which a short stair leads to a square ring-shaped walkway where the Wormsign event takes place. The Sacellum is therefore home to the Unique Monster Fenring, who appears during the event.
