Here we have some members of the Red Ridge tribe from Pathfinder Society #6-11: The Slave Master’s Mirror! As proper Gnolls, they never go anywhere without their dire hyenas. If you meet them on Stonespine Island, take care they don’t make you into their newest slave… or their next meal!

They’re the Hell Hound from Reaper:
