The older the sun, the warmer it is, making Realmspace the oldest of the known spheres. There are dark splotches of cool areas, known as sunspots, though even those are too hot for humans to survive in or near. Lakes of molten earth and liquid flame are the most common feature of the land. There are hundreds of openings to the Elemental Plane of Fire, which has served as a point of immigration to Sol. It’s believed that the “smell” of the sun is quite pleasant to fire-born creatures, making it a desirable home, though a contravening theory is that the inhabitants are refugees, fleeing the tyrannical rule of their races on the elemental plane of fire. Some say that spelljammers made of pure fire have been tested by the natives, but none have ventured out as far as Anadia. Whenever a ship strong enough to survive the flames gets near the sun, it is attacked by the inhabitants, and must either turn back or be destroyed.
