Some League Fortress features are initially only available to the League Marshal. To allow other League members to use League Resources, or to rename or relocate the League Fortress, the League Marshal must give permission to those users from the "My League" tab at the League Hall.
To edit the privileges afforded to other League Members, open the list of League Warriors and tap on a fellow League Member's Rank icon. You will then see the list of Ranks. Press the arrow next to any of these to review and manage the Privileges granted to Members who are of this Rank.
Every fully-fledged League Member can contribute to the defense of their League Fortress, as well as any attacks on other Leagues' Fortresses. They can convert Resources to League Resources to help develop the League Fortress. They can also help upgrade the League Fortress and Fields of Knowledge by participating in Tournaments and League Quests to earn Tomes and Glory Points.
League Marshals and other authorized League Members can view their League's Resource history from the "History" tab at their League Keep. If a League Member leaves the League, all Units they have garrisoned at their League Fortress will be sent back to their Catacombs. However, all League Resources gained by them will remain in the League Account and will not be returned to them.
