History of Chaos Castle
Chaos Castle |
Chaos Castle was created by Lugard, god of the celestial world, and Secrarium, god of the underworld, with the purpose of maintaining the balance between good and evil in MU Online. However, travelers began to favor Lugard, breaking the established balance. To restore order, Secrarium proposed that all participants use the Armor of Guardsman, a measure that Lugard accepted trusting the integrity of the players. Despite this trust, the darkness in some travelers’ hearts caused internal conflicts, transforming what should have been a balance event into a scene of chaos and constant rivalry within Chaos Castle. |
