The point of this is being a fan RP, which is just like a normal RP site, but you use your own fan made character. So in order to do that, you have to create that characters biography. This will be the basic set up of the FMA charcter bios.
Name: (character name goes here)
Occupation: (Alchemist, Military, Automail Mechanic, etc..)
State Certified: (Applies to Alchemists only. Are you a State alchemist, or just a normal alchemist.)
Description: (give a description of what your character looks like)
Special Skills: (This would either be where you put your main study of alchemy, such as bioalchemy, flame alchemy, etc.. or where you'd put your special military training, such as marksmen, communications, etc..)
Back Story: (your characters background story goes here)
quick note to those who choose to be an alchemist: Please try and avoid putting something about doing a human transmutation and seeing truth in your back story. I don't want a million people being an alchemist that has seen truth so now they can transmute without circles.
also I don't think being a homunculus would work out to well. if you want to give it a shot, go ahead. I won't stop you unless things start to get out of controll.
