Lingering Evil

The lingering evil is what was left of the crafters forces after barad thun.

While the most dangerous beeings got slain or driven away during barad thun, many more careful creations of the fallen crafter flet into the swamps and eternal dark places of the world to hide from the bright forces of "the heavenly realm"

There are:

Golbins

Orcs

Dragons (some did not bother fighting for the crafter and stayed hidden because they did not see a reason why to leave their cave)

Wyrm

and all kinds of aberations and failed projects by the crafter
