I've almost got a character, just having trouble thinking of specific abilities. I'm going with a Mage with affinity for darkness. I'm going with that it's a strong magic, but it physically harms my character if he uses it too much or if he loses control of it. I just need to think of some related magic he might have and a more full backstory. So far I've got he was an outcast in his original home in North America because darkness has a negative stigma, then he goes to Japan, finds out about the detective agency, and joins to prove to others (and partly himself) that he's not inherently evil just because of his magic. Would that be s good enough backstory if I wrote it out in full sentences?
