Hathrox IV is a relatively stable planet. Although volcanic activity remains present, the planetary life cycle has come to a more agreeable state. Due to the fertilizing effect of the volcanic ashes expanding vegetation has come to exist on one part of the planet, right in the middle of the icy plains that still cover most of the surface. One day this planet might have become one big, lush forest. Nowadays only the unexplored caves give reason to travel to this location. They are still very dangerous though, since the planet is getting warmer and water from melting ice floods the caves and sometimes makes them collapse. A crater in the south shows evidence of a ship that must have crashed here, but even the local inhabitants know nothing about it.
