Omgi Ztehh
From Myths of Atalan Wiki
The Omgi Ztehh is a dark, dank, fetid mire of deep waters and darkness, an overgrown swamp where the dead walk, a place where even that which lives, is in slow decline, into the mire and murk.
Trees grow out of the murk, creating a thick canopy that allows only some light to pierce, light slowly choked away to the faintest touches that reflect off fetid waters sickly. Mangroves, tangles of great roots, make an almost maze-like depth of dangerous, confusing tangles, but along the edges of the swamp where the Orcs live, these have been cleared to allow space for them, not only to live, but to do battle with the endless undead. The undead are said to spill out in all directions from the deep waters, particularly towards the woods to the west.
