Demonsgate is a planetary object within the Kathol Rift and lies considerably closer to its star than the other planets in the system. This extreme proximity has caused the surface of the planet to be somewhat unstable due to the gravitational fluctuations and heat produced by the nearby solar body. These extreme effects are continual stresses on the planet's surface that cause volcanoes to erupt in a large number of places and with such violence that if they occurred on any other planet, it would have been abandoned long ago.

All the water on Demonsgate is encapsulated within pockets underneath the surface; the surface water has evaporated long ago due to the extreme heat. Occasionally, one may see magnificent geysers erupt from the surface. These eruptions are caused by magma contacting the underground aquifers and superheating them. This incredible pressure pushes the steam up through cracks in the crust and into the atmosphere.

One unique aspect of Demonsgate that attracts certain types of beings is the illusion that the planet is on fire. The optical effect is caused by the ionized particles released through the volcanic activity on the planet interacting with material surrounding it. It has been determined that the nebulous clouds of the Kathol Rift enable the phenomenon since it is composed of the fine dust and gases needed to cause the reaction.

Despite the harsh environment and its dangerous peculiarities, the planet is not in fact lifeless. Many indigenous creatures call it home, although none of them have reached a state of sentience yet. Due to the terrain and location of Demonsgate, it has also become a favorite training ground for a dark and mysterious group that has taken control of the surrounding area.
