Dechôz is a region south of Weretopia. The western coasts of Dechôz give way to the Mephigax. One of the largest and most civilized populations centers of this region are those of the Talaxans.
The Underdark region beneath Dechôz is called Ikešai. Both of these region names are Supernal, named in the Dawn Era by then angel Arcana.
