Korra probably still counts as human, but spirit ties would be interesting! Ahad doesn't always pay attention, but I feel like being tied to a spirit of light would be kind of noticeable?

As for Jason, the terms are different, but demigods in Ahad's universe kind of occupy a unique position. Demigods are called demons, and their blood can kill gods/godlings. (As for Inheritance Trilogy stuff: There's three gods in this universe, who had immortal children called godlings. Humans were more of an experiment, made by one of the three. When a human and a god/godling have a child, boom it's a demon.)
