Quartermaster Dekrok

Quartermaster Dekrok is an orc general goods vendor found at the Dark Portal in the Blasted Lands.

He's quite peculiar, having the red skin of a fel orc, a look shared by some Horde Portal-Sentries. It's unclear if this means that they are fel orcs who have joined the New Horde or if their appearance is a developer mistake.

It's unknown if he survived the Ironmarch.

Speculation
It's possible that the radiation from the Dark Portal altered his skintone, or Dekrok is one of the forcibly corrupted fel orcs under Illidan freed by the Horde.
