You find yourself looking on a planet with no water, with mountains of crystal and quartz, lifeless. Or maybe not.
This planet is filled with crystal human hybrids and their lesser and greater cousins. There are several Crystal nodes on the surface which will endlessly spawn these hybrids, the nodes can be destroyed and will not dominate your mind like their threats imply. There is one cave on this world in which you are surrounded by crystal walls, which are indestructable, and more Crystal nodes. What is further than this is unknown...Unless you are in possession of a certain Alien Artifact.
Note:There is a bug where you can only advance partway into the tunnel system before prospector will always crash. Unknown cause, planet label:The Planet of Crashing.
