Keepers

Keepers are the protectors of each world. Many of them will appear in different areas as you progress farther on the map. Each one of them have 50 levels. Every time you defeat a keeper battle you will remove 1 threat. As you win keeper battles, the enemies will become more difficult so it is important to level up the keeper as you progress.

Some keepers will be locked. This is because you do not have them in your army. In order to unlock those keeper you must summon them.
