Grislings are the last race, and it's not clear exactly what element made them what they are; some posit that a strange mixture of cold and shadow had to have created the grislings. Many of them come from the dark realm of Nevregal, where the sun rarely rises, although they can be found in reasonably large numbers in Rodach, Kharnimrion, Hombarast and the Valade Holds as well. Characterized by pale gray skin, and white or silver hair and eyes, the grislings are occasionally called the Colorless as an insult; although it's not inaccurate in any way. They tend to be somewhat aloof and quiet, many of them speak in a voice that's little more than a rasping whisper.
Many of them have also more recently relocated to Kochbin, one of the few places where those with a tendency to tinker and invent can find kindred spirits and a culture that values their input; many other cultures are skeptical of their tendency to mess with things and change them; especially hide-bound cultures and individuals (especially dvergs) may indeed find them obnoxious. However, grislings are not all tinkerers and inventors, of course, and many use their quiet confidence in other ways; cat-burlers, assassins and other sneaky professions are (stereotypically) sometimes occupied by grislings as well.
A grisling has a racial affinity for Stealth as well as a +1 to any Tinker or Athletics skill checks.
