Messen is the third world in the Rhoie system. It is a giant jungle world, dominated by several volcanic mountain ranges. Classified as a death world, the few smaller settlements wage a continuous war with the encroaching jungle. The dominating animals are large reptiles, similar to the dinosaurs of ancient earth. The only city is called Karakon and is built around a smaller space port, which mainly trades with the valuable pearls that can be found in the ears of the giant reptiles. These pearls are very valuable and is the only reason there are humans on Messen. Eldar has repeatedly been sighted in the area, and the Inquisitors suspect that Messen may be one of their Maiden Worlds. No confrontations have so far been recorded.
