Server schedule
Events
The siege runs once a week; everything else runs every day, at the same time. The countdown is worked out in your browser from the server schedule, so it is right even if this page came out of the cache.
The castle
These three run on the castle server, a separate process that loads Valley of Loren, Crywolf Fortress and Land of Trials. You reach it from inside the game, on foot: there is nothing to install and nothing to pick on the login screen.
| Event | When | Next |
|---|---|---|
| Castle SiegeThe battle for the castle, in Valley of Loren. Two hours, once a week, and the only event on the server that ends with an owner. The week before it has the sign-up and the guild mark: the phase table below says when. | Sunday, 3 PM to 5 PM | 20h 30m |
| Castle DeepWaves of monsters inside the castle map, three times a day, half an hour each. No sign-up and no guild needed: whoever is in Valley of Loren gets it. | 4 AM, 12 PM, 8 PM | 1h 30m |
| CrywolfDefence of the altar in Crywolf Fortress against Balgass and his invasion. On this server losing costs nobody anything: the experience and jewel drop penalty is switched off in the configuration. | Wednesday and Saturday, 8:30 PM | 2h 00m |
The siege week
The siege is not only the battle: the guild has to sign up and register its mark BEFORE, in windows the server opens and closes on the clock. Anyone who finds this out only on battle day loses the whole cycle and waits for the next one. The dates below come from the same state table the server reads.
- Guild sign-upMonday 12 AM until Tuesday 11:59 PMnext Oct 12The guild master registers the guild to attack the castle. Outside this window the server refuses the sign-up, and there is no second call: miss the window and you wait for the next cycle.
- Guild mark registrationWednesday 12 AM until Thursday 12 AMnext Oct 14With the guild signed up, the master registers the Guild Mark. It is a window of its own, separate from the sign-up, and the server also only accepts it inside that window.
- Castle preparationFriday 12 PM until Sunday 3 PMhappening nowThe server closes the list of signed-up guilds and prepares the castle. Nothing to do here: this is the part the server does on its own.
- The battleSunday, 3 PM to 5 PMnext Oct 11Two hours in Valley of Loren. Whoever takes the crown keeps the castle until the next siege.
The castle went live on 12 September 2026. What is proven: the castle server program has the siege module inside it, the three events are switched on, the times come from the files that program reads, and a player on a phone has already walked from Lorencia into the castle and back.
What we have not seen happen yet: the first occurrence of each of the three. The countdowns above say when. If any of them does not happen on time, this page is corrected the same day, and the reason is written here.
Event rooms
These three open for entry at the times below and start once someone registers at the NPC. This is not fine print: event rooms in MU do not run by themselves, and promising "starts at 2pm" would be selling something the server does not do.
| Event | Times (every day) | Next |
|---|---|---|
| Blood CastleA race against the clock to recover the archangel weapon. Enter through the Messenger of Archangel NPC, in Devias. | 12 AM, 2 AM, 4 AM, 6 AM, 8 AM, 10 AM, 12 PM, 2 PM, 4 PM, 6 PM, 8 PM, 10 PM | 1h 30m |
| Devil SquareA closed arena with waves of monsters and a points ranking. Enter through the Charon NPC, in Devias. | 12:30 AM, 4:30 AM, 8:30 AM, 12:30 PM, 4:30 PM, 8:30 PM | 2h 00m |
| Chaos CastleEveryone against everyone in a shrinking arena. Fall off the platform and you die. Enter through the Chaos Goblin NPC. | 1 AM, 3 AM, 5 AM, 7 AM, 9 AM, 11 AM, 1 PM, 3 PM, 5 PM, 7 PM, 9 PM, 11 PM | 30m |
Invasions
These need no registration: the monsters show up on their own in the open world and stay for 10 minutes. There are 8 a day, every 2 hours, and the server log shows them firing at these exact minutes every day.

Running, but with no fixed time
These are enabled on the server and have no timetable: they follow the event's own internal cycle. We would rather say so than invent a clock for them.
