The Citadel of Ferumbras is one of Tibian's scariest places, located on the forbidden island of Kharos. Some consider it the scariest right after the Pits of Inferno. This tower is filled with evil creatures including Liches, Dragon Lords, Serpent Spawns, Warlocks and Demons. The tower was sequestered by mages from the Edron Academy.
