Hunger: healing.
Prime power: light.
Homeworld: ZenithThe world of the People of the Sun. More, which is very hot, has numerous major stars, and is clean, regimented, and always welcomes those who are sick and require succor.
The People of the Sun bred for fire, light, heat, as a means to burn away infection and evil. This power grows over time; toward the end of their natural lifespan, their physical forms can no longer take the strain of magic coursing through them, and those who are the most ancient and venerated grow hotter, and hotter, and eventually explode into ash.
