Guilds & Alliances

How guilds work in MU Online: the Guild Master NPC in Devias, guild and alliance chat, guild commands, Guild Matching, guild wars and the role of alliances in Castle Siege.

Guilds & Alliances
8 Nov 2026

Founding and joining a guild

Guilds are created and managed through the Guild Master NPC, who stands in Devias, the snowfield north of Lorencia (characters need level 15 to enter it). See Towns & NPCs for the other important NPCs.

To join, point at a guild leader and type /guild to ask to be accepted. Guild size depends on the leader: an older fan guide notes that a Dark Lord Guild Master with a lot of Command can hold up to 80 members.

Guild commands and chat

CommandWhat it does
/guildAsk the guild leader you point at to accept you

/warDeclare a guild duel (add the other guild's name)
/battlesoccerChallenge another guild to Battle Soccer (add its name)

Guild Matching

Guild Matching is part of the same Matching window as party search (see Party & Matching). It has a 'Find Guild Members' side for guilds that recruit and a 'Search Guild' side for players looking for a home. A small alert icon flashes, with a sound the first time, when someone asks to join. Recruitment posts are wiped during the last scheduled maintenance of each month.

The Season 20-1 third update reworked it:

  • A free-text Guild Introduction (up to 100 characters) replaced the old interest and class boxes, and the wanted level is now typed in directly instead of ticked.
  • Join requests are accepted or refused with O/X buttons right in the recruitment tab.
  • Clicking a guild in the list shows its mark, average level and introduction, and joining asks for confirmation.
  • The old guild window was merged into a new Guild Information tab.

Alliances and Castle Siege

Alliances matter most in Castle Siege, the war fought in the Valley of Loren. A guild that wants to take part needs a Guild Master of level 200 or more (any class) and at least 20 members, and it needs an ally to use the castle's features properly. Only three guilds plus their allies can join a siege; other guilds and players can fight as neutrals but cannot win the castle.

  • Only the Guild Master of the main alliance can announce the siege at the Guardsman NPC; then any member of those guilds can hand in Marks of Lord to raise the guild's rank.
  • The guild that holds the castle, together with its allied guilds, can warp to it through the Loren canyon and may enter the Land of Trials.
  • If the castle-owning guild disbands, it loses the castle.

Guild wars

Besides the siege, guilds can fight each other directly with the /war and /battlesoccer commands. The eX700 expansion of 2012 also added a larger guild war system called Arca War. For other kinds of player fights see PvP, Outlaws & Duels.
