Overlord Ror
Overlord Ror is a black Deadwood Furbolg, a bit bigger than his soldiers (3-4 Deadwood Warriors and/or Deadwood Pathfinders). He's level 51, but not an elite. He has a 
[Fear] power, which has approximately 10 yards of range. This ability appears to be a random proc, and may be used multiple times in a fight. Items that prevent fear spells work normally.
