Luca is a bit of a Mama's boy, as he doesn't have to fight for her attention (unlike his siblings). When his mother isn't around, Luca attends to his kingly duties in the Highest Lands. He organizes the activities of restless angels, as well as communing with living mortals who call out to him from the Mortal Realm. He doesn't control the sun, but his magic is significantly strengthened by its light. His magic stimulates memory and thought, but suppresses emotion.
