"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."
"It's very easy to enter Chaos Castle. To enter, simply right-click your armor at the appropriate times (12 AM, 14 PM, 16 PM, 18 PM, 20 PM, and 22 PM). Players in designated locations, such as a PC cafe, will have more opportunities to enter. You will stand by for about a minute before actually entering. The event starts once this standby time passes. Once it does start, travelers and corrupt guardsmen will fight each other to the death in a no-holds-barred melee. It doesn't matter with the travelers, but you have to be careful when you kill a corrupt guardsman. Corrupt guardsmen will explode and may even push you off of the arena. If this happens, you will be disqualified. If you want to find out when you can enter, simply move your mouse over the Armor of Guardsman. If you want to enter, simply right-click on the armor at a designated time."
