Squires may go to Knight or Soldier. Soldiers can go to elemental classes. Knights go to the nature class or the Mystic class. Once they become Elders, they may choose a different class that they can start from and level on. The Light element is the last class anyone can go to. You can not go straight to a certain class. You must follow the rankings. You must always start out as an aid and follow the rest. Once you reach Soldier and are allowed to level, you can choose a certain element, then follow that element. Once you reach Elder, you are allowed to choose a starting Soldier class.
