The Furies are a mixed race of demon-like entities. To say they are hostile is the understatement of the century. They hate all sentient living things and regard them only as slaves. Very little is known about them, but they claim to have ruled the Earth untold Eons ago. If this is true, perhaps a few mistakenly wandered into a time crossing rift and ended up in our time.
They have a keen understanding of magic, and all seem to use it. Luckly, their numbers started small, but an increase in Fury held land points towards a growing population.
If we were able to interrogate one, or perhaps look at its genetic makeup, we might get a peek into Earth long and dark pre-history. If they understand magic so well, there must have been many more “ages of magic” long ago. Are they alien to this world, or a natural evoltuion of some pre-historic beasts? Are they lying and simply exist in a diffrent timeline? If we knew what rift originally spawned them, perhaps we could get some answers. This is indeed one of today’s great mysteries.
