I'd say that races that most similarly resemble each other are possible and might be somewhat common. I could see Humani/Elvish, Humani/Dwarvish, and Elvish/Dwarvish being existant and decently common. Thoughts? [@Emuxe]

Well, more common than other hybrid breeds, but still relatively uncommon. It'd be like a cat trying to mate with a lion, it just wouldn't work too well.
