Mission Basics

From AethoraWiki

You can spend all day fighting in the two Hopitan Arenas, but if you want to discover some of the other areas in Aethora, you'll need to take on some missions. Completed missions will open up more of the world as well as reward the player who chooses to take them on. Be wary: often times a mission will be harder than your run-of-the-mill encounter.

If you can't find any missions, check this page to find a little more info on where missions start and their requirements: Missions
