I definitely want to join this, looks like fun. 

I was thinking for my character she would be born from blood spilled in battle of the God of the Water/Ocean, mixing with the salt waters of the sea. Her immediate sphere's of influence would be battles at sea and female warriors, more specifically those born close to the ocean. I was thinking the place she was claimed to have been born could be called the "Boiling Sea" since it is said the heat from her birth caused it to forever boil. 

Just a rough idea, but what do you think?
