Short-tempered, spiteful, and bitter, Halvatt is the twin brother of Ren Tarasa and a child of the creator god Atei. Born missing a small but vital fraction of his magical composition, he blamed Ren's unexpected birth for robbing him of what was his by right, and thus hated her deeply for rendering him 'incomplete'. Serving primarily as an agent for his father, with whom he has a difficult relationship, he studies magic with extreme dedication and vows to become as the gods themselves, in spite of being fenvasi by birth.
At his core, he is a harsh, cynical individual that deeply depises himself just as much as he despises others. He does not spend much time around others and he takes great pains to avoid his "humanity" by refusing to perform basic, normal functions that gods would not need, such as eating. Halvatt has a superiority complex due to his heritage, acting quite cruel and condescending to those around him at times, though it seems like he's...working on it...? His special talent is being able to turn anything around him into a highly flammable object.
