Omphuvax is desert of southern Voternil. It was created in the Second Marwing War when Spirachiln tried to annex the area from the Kezgaer Confederacy. The goblins, kobolds, and other humanoids of the forest Faehion, the Taurion valley, and the mine pitted hills of Rulamirnur united to confront superior forces. They also had to contest with numerous fey which inhabited the Tendrils advancing south from Marwing; which is itself just a smaller forest inside the great Taurquion forest. They turned to Blighters and arcanists skilled in deforestation, to meet the dual threat. They did so much damage to the forest that it turned to a desert. Even today, hundreds of years later, only the hardiest of plants can root here.
