How to register guild for castle siege?

Guild Leaders can sign up their guild at the Guardsman NPC, located in:
Valley of Loren (99, 61)

Registration is available Monday to Thursday. Only the Guild Leader can submit the application.

Sign of Lord Collection & Registration

The second requirement for joining the Castle Siege is collecting as many Sign of Lord items as possible.

This item is extremely important—any guild aiming to enter the siege will actively farm it, as the total amount gathered determines which guilds qualify.

To improve your farming efficiency, make sure to configure your MU Helper to automatically pick up Sign of Lord. This ensures you collect them consistently while defeating monsters.

Once your guild is registered for the event, all gathered Sign of Lord items must be submitted to the Guardsman NPC.

Castle Siege Combat Zones

On Sunday, qualified guilds gather in Valley of Loren for a massive multi-guild PvP battle leading into the Castle.

Valley of Loren is split into three main stages:
1. Outer Zone (Mark #1)
Open-field PvP zone. Any player can attack another.

2. Castle Zone (Mark #2)Inside the castle walls — protected by multiple gates and war machines.Gates have high durability and must be destroyedWar machines can knock players out of the castle

How to Capture the Throne

Switch Mechanic
Two switches are placed at the lower part of the Throne Room. Both switches must be held by the same guild to unlock the Crown.
When the switches are secured:

Reward for the victory

The Guild Master of the victorious guild is crowned the Castle Lord.

To enter the castle area, speak with the Gatekeeper in Valley of Loren (139, 100), right outside the castle entrance.

Inside the Land of Trials, you can fight Erohim, the main boss.
Erohim can drop up to 10 Ancient items—one item per guild/alliance member present, with a maximum of 10 total.

Example:
If only 9 members of your guild/alliance are near Erohim when he is defeated, your guild will receive 9 out of the 10 possible items.

⚠️ Notice: The Lord Mix is operational; however, it does not return items after the mix is completed. Please do not use this feature.

⚠️ Notice: Only one spot will be available in Land of Trial and it will not drop any ancient items.

⚠️ Notice: Each member must hit Erohim at least once to be counted as present and eligible for the drop of up to 10 Ancient items.
