I understand that Ratskins may be a Necromunda specific tribal society, but it stands to reason that similar tribes could spring up in any underhive society or environment. Be they worshippers of snakes, sludge, rats, mutants, or other abstract ideas.
Using the Ratskins as a basic template for Underhive Natives, or Feral Hive Worlders, what origin fits best for them? Feral Worlder? Hiver Worlder? Pick and mix both?
Dont get me wrong, I have something I am working on so it isnt that I dont have a clue or notion to go on here, but Im just trying to pick the hive mind collective brain here before I start typing.
