This is a cross-cultural game. There may be creatures from real world cultures and along with that, there may be the possibility for culturally insensitive actions. To combat this, we have a few guidelines to help you think about how to potentially portray characters with different cultural backgrounds.
Be respectful of the cultures you are portraying. Do some research, understand both the history and the present. Understand that cultures are made up of real thinking and feeling people and try to build on cultural portrayals from those people. Also, recognize that this content comes from living cultures. If you want citations or links, feel free to ask the ST staff.
Do not feel that you are limited in your character choices by your own ethnic and racial background. Within the universe, gods frequently adopt the children of other gods, sometimes because of personal infertility(Osiris is lacking certain procreative attributes, for instance) or because of strong affinity. Additionally, gods can manifest in many different ways. Your mortal parent might not have been impregnated in a normal fashion, what’s to say they will receive genotypes in a normal fashion(what chromosomes did you get from the swan, Leto?).
Do not attempt to costume as someone from a different race using makeup. This is especially true if portraying someone of African descent, but is equally true for other cultures. Recent history has shown fairly clearly that this cannot be done in an inoffensive manner. If you have questions about this, feel free to ask the ST staff.
All in all, this is about being culturally sensitive, not about restricting ideas. But we as an ST staff are open to helping. Feel free to get feedback from the ST staff on potential ideas and we will try and workshop things with you to try and avoid culturally insensitive depictions.
