Phenex

Phenex is a prince who will never become king, but "Prince" is more of a human title- he is the Prime, aka an immortal demigod whose birthright is a special mission. He is to investigate the abandoned temples of the Veiled Lady (a death goddess!) and hopefully figure out what exactly happened in her residences before she vanished. Instead of doing this, though, he ganked her all-powerful trident and now shes back with a vengeance
