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.

Enter as one of 10 MUtizens to engage the forces of Kundun as they spawn in front of you in a endless barrage of attacks. Either alone or in a team only the strongest will survive the Devils Square. With the Devils Invitation, you are granted access into the Devils Square, where your strength will be tested. .

Olga, the Shadow Phantom Soldier, says: "Chaos Castle is a battle field created by Lugard, the god of the heavenly world, and Secrarium, the god of the underworld, for the balance of good and evil in this world. However, travelers started going to Chaos Castle and fighting on the side of Lugard, tipping the balance in disfavor of Secrarium. To restore balance to the battle event, Sacrarium made Lugard an offer and suggested the implementation of a new rule. This rule was for everyone participating in the event to wear guardsman's armor. Lugard, believing the offer to be fair, accepted it."

"Unfortunately, Secrarium was betting that darkness in the hearts of the travelers would ultimately lead to hostility and discord among them. Lugard was also aware of the travelers' dark side, but his trust in them didn't waver. Eventually, as the dark god predicted, the travelers began to feud with one another, and Chaos Castle became increasingly... chaotic."

This event is held in the Valley of Loren with the goal of killing as many mobs and the boss Erohim as possible.
