Haelrahv is a mixed bag of science fiction and fantasy, leaning more toward fantasy. While high-tech weapons, droids and other devices are a part of the world, so are magic, psionic abilities and classic weaponry.

Haelrahv is not combat-oriented, though combat is a significant feature. Players can choose from twelve distinct classes and five races. All of the races in Haelrahv are completely original other than humans.
