The Chamberlain assists in the defense and reinforcement of the castle

The Castle Vault contains all money obtained through taxes, and is used for the purchase mabinogi heroes gold of manor seeds. The castle lord may withdraw or deposit funds from the Vault at any time, but should be conscientious about managing the castle funds.

The Chamberlain also assists in the defense and reinforcement of the castle in between sieges. He can open and close any or all of the castle's gates, banish all outsiders that do not belong to the castle-owning clan, and oversee the upgrade and reinforcement of castle gates, walls, and siege traps.

In addition, he also provides special certificates that can be used to recruit allies into the Army of Dawn and help prevent revolutionaries from weakening their defenses through the Seven Signs Quest.

Finally, mercenaries may be purchased through the Mercenary Manager. These mercenaries are positioned throughout the castle immediately before a siege and will defend their positions with their lives.

In addition, the Wyvern Manager stationed at the top of the castle allows a castle lord with a powerful Strider pet to mount the fearsome flying Wyvern and assert his lordship over both domain and battlefield from the sky.
