The Lost Tower is a massive tower located in the northern part of MU, within Devias' snowy wilderness. Once a place of great achievement where a sorcerer successfully opened a portal to Icarus, it has now become an utter wasteland after Kundun's plunder. The tower consists of seven floors, each inhabited by dreadful monsters assigned by Kundun. At the top resides Balrog, a formidable beast wielding a scythe, awaiting any who dare to challenge him. Few warriors in MU can compete with him, making the Lost Tower a perilous yet enticing destination for adventurers.
