Even the long-lived elves cannot remember a time when the undead did not plague Xin. Their attacks on the Walls of Suin'ai come intermittently and sometimes there is not a sighting for a decade. Without fail, they always appear again.
Some are little more than shambling zombies of various races, other are more disturbing, and terrifying creatures found only in the darkest corners of one's mind. No one knows their origin or how they seem to constantly replenish their numbers, but the eternal damned roam the wildlands of Xin. Below the earth, drow forces keep them out of the intricate underdark tunnels. Along the coast, elvish ships patrol and special magi, trained for centuries, keep watch below the water, but thus far, the undead have seemed disinterested in walking below the ocean's surface... enough have tried, however, for the living to fear...
No living civilization is known.
What god can help you here?
The dead do not discriminate.
Are all around you.
