The Durth'Nyrok

DURTH'NYROK [Dur – 'TH / Neye - ROCK] (Unknown – first encountered early 2nd Age) 

“Doom Shadow” Gorgoth; hulking dusky skinned Gorgoth that serve many as mercenaries throughout a number of dimensions. Their base is now located in the Crystal Villa, from where they sell their services to whichever beings need their strength, and they are rare amongst Gorgoth for being both trustworthy to their employer (assuming they are paying the most) and exhibiting sound tactics in battle beyond simply roaring and charging. Their standard is a jagged gorgoth skull, composed of stylized bolts of black lightning and fire.
