Editing Derro (section)

==[[Pathfinder]]==
When [[Pathfinder]] learned they could get away with bringing derros into their own game, they decided the best way to do it was to try and more explicitly use the themes of the original Dero stories, which is expanded upon in the sourcebook "Classic Horrors Revisted".

Derro on Golarion are actually corrupted fey, descendants of the same root-stock as the [[Pech]], but diverged from them centuries ago when they fled a civil war amongst their race that brought them towards the surface. A combination of starvation, struggle and addiction to the one source of nourishment they managed to find, the brain-altering and toxic fungus cytillesh, caused them to mutate into their current forms, whilst also afflicting them with racial insanity and wide-spread infertility.

This keeps the derro a fairly rare race, and this is a mercy; obsessed with understanding why the residents of the "Overburn" are not affected by the sun's rays in the way that they are, the derro conduct a ceaseless campaign of experimentation, performing all manner of insane and unholy regimes of gaslighting, dissection, vivisection, grafting and other forms of [[fleshcrafting]] - worse, because of their insanity, derro do not pass on the fruits of their labors, meaning that the race's goal is impossible to achieve, as each generation dismisses the works of its predecessors and starts over from scratch. They conduct endless nocturnal raids on the cities under which they establish their lairs, covering up their depredations with crude brainwashing (surgical, [[psionics]], or both) and assassination. Vicious cannibals, the only races they typically interact with are [[grimlock|morlocks]] and [[mongrelfolk]], whose flesh they regard as inedible.
