The Sun include any magical beings with a primary drive and ability to heal.
The name of their parallel world is The world of the People of the Sun. More, which is very hot, has numerous major stars, and is clean, regimented, and always has places for sick people to come for healing. As they grow older, the people of the Sun grow more powerful, but their bodies do not adapt to this change. Toward the ends of their lives, their physical forms can no longer take the strain of power coursing through them. Aged members of the sun essentially experience spontaneous combustion, exploding into ash.
