Fortunately this RP doesn't require any heavy amounts of knowledge of the universe. It helps, but it isn't necessary. In fact, what we're dealing with currently might sound familiar to anyone who has any familiarity to early renaissance europe/late medieval Europe coupled with bits of fantasy. The roleplay is currently taking place in the human capital of Stormwind, which should be quite familiar to most.

We have room for a lot of playstyles. We're only 3 so far(4 with you).

Do you want to be an engineer of sorts, tinkering with crazy gadgets? or a holy paladin/priest? a merchant type who deals in all things of wealth? Maybe something to do with magic? or a hybrid? Or just an average peasant in the wrong place at the wrong time?

We are not limited by the ingame classes in this RP. You can play as whatever you want as long as it is within the realms of reason. 

The current group setup has a lot covered already(magic, physical and alchemy), but we don't have a holy/divine character for that matter.
