CASTLE SIEGE
Castle Siege is the largest guild-versus-guild event in MU Online, where guilds compete for control of the Castle of Valley of Loren. The defending guild must protect the castle while attacking guilds attempt to capture the Castle Crown and become the new castle owner.
The victorious guild receives exclusive control of the Land of Trials, access to the Lord Mix, and weekly cash rewards until the next Castle Siege.
