From Eden Eternal Wiki
Halfkin are a playable race in Eden Eternal, realeased on November 22, 2011.
Ancient legends say the Halfkin were born of a quirky mother who collected--of all things--teeth, and a diminutive red-bearded father whose footprints were all colored like rainbows. In reality, no one knows where the Halfkin came from. All that is known is that they are more playful than a Zumi, more mischevious than an Anuran, more tenacious than a human, and...well, perhaps not MORE powerful than an Ursun, but at least AS powerful. Those who don't take the Halfkin seriously as Guardians are making a mistake--a mistake they'll only make once.
