Unplan-etary Formation

Unplanetary Formation is caused by the spontaneous creation of an inverted planet, one with the Interior being fertile and bright, and the exterior being surrounded by magma/lava. It is not yet understood how the planet creates this interior brightness and heat, however our brethren are researching this phenomenon.

Just like on stars, there are cooler points on the planet's exterior, where the magma/lava cool enough to form small landmasses.
