The Epic server has missions that progress are a part of the 1st scenario. The scenario is the powerstruggle of the gods in which players can help. This is done by helping spirits that can travel between Valei the home of the gods and the gameworld were the players live. The gods are looking for "collectables" and have a movement of 1 step for every 3 real life days. (With an exeption if are in a labyrith.) Doing missions can speed this up. Unfortunately theres little known what the collectables do. So the powerstruggle seems very vague and uninspiring. Theres no real fight or something it is more like a race to get the most collectables. There are also source tokens, they seem to be bonusses. What they do is also unknown to me. Here is a map of Valei and the last moves of the gods:http://hom.creative-realms.net/valrei2/last.html
The missions are Kingdom wide and is giving by there faction god.
