Harpies are a race of monsterous humanoid women with wings on their backs, tails, and legs of raptor type birds.
Harpies are just as intelligent as humans. Arcane magic is rare among them, but alpha harpies are often cleric types of sinister gods.
Harpies live alone or in extended “family” group communities. They lack any serious industry beyond simple home crafts, but are savy enough to trade or steal for useful goods, especially weapons and magic items.
The origin of harpies is uncertain, but they seem to be a kind of magical hybrid sub-species. Possibly due to an ancient curse or breeding with some supernatural beings. Either way, they are all female and require the use of humanoid males to reproduce. They can breed with humans, elves, orcs, goblyns, and hobgoblyns, but the species of the father seems to have little to no effect on the nature of the newborn harpy.
Harpies generally despise other races, but will work with them on occasion. Even so, their “mates” are most often the mind controlled victims of their hypnotic singing ability. The mesmerism doesn’t last beyond the harpy singing, and usually neither do their mates. After all that work harpies tend to be quite hungry.
