What is the Blood Castle Event?
Risk your life to save the Archangel One of the strongest warriors in the Continent of MU, the Archangel; has secretly been laying watch over the lands that he has sworn to protect. As Kundun presence approaches, the archangel has been warding off all the monsters trying to invade the Continent of MU. But alas, our Guardian Archangel can not fend on his own forever.

Kundun Army has invaded his Castle and has overcome the strength of the Archangel. The Archangel, injured and in peril; summons forth the warriors of MU, to come aid him in his most dire time of need. Unable to summon his strengths without his Divine Weapon of Archangel, you have been asked to infiltrate this now over ridden Castle and retrieve his weapon for him.
