I'm not that troubled by their saying "dark fantasy fiction." Maybe they're trying to say that the don't publish poetry or dramatic scripts?
Frankly, far more worrisome is "Venture capital funded, Ghost Pines Publishing was founded by a team of seasoned entrepreneurs with a successful record of turning leading-edge concepts into profitable business ventures." What I interpret that to mean is "We're folks who don't have a clue about publishing." That sort seldom come to a good end.
