Oh welcome. Well the character sheet will be up tomorrow. The rules are pretty standard, no god modding, try and get along with each other, try not to one line to much ect. Now regarding what gods you can pick no hestia or Artemis children as they are among the virgin goddess. You will be allowed to be a follower of Artemis though and be a huntress. 
Other than that additional rules will be added later. Oh also try to keep it original. I'm not saying there can't be more than one child of the same parent but try to keep it original with what god you choose.
