Skyforge blog post on the game's official site. It's all about adepts, which in case you've forgotten are the loyal followers of your avatar who further your personal power and assist you on the road to godhood.
Adepts distinguish themselves from your regular followers by way of a profession: Engineer, Templar, Sorcerer, Mystic, Preacher, Healer, Envoy, or Agent. Some adepts are better suited for particular missions (send a Healer on an epidemic curing mission, for example), and adepts who successfully complete missions will bring you gifts and additional followers for your trouble.
Adepts also help you gain reputation within the game's provinces, so it's in your best interest to develop their power as efficiently as possible. How do you do that? Well, you can start by reading the dev diary which we've linked below.
