Humans

Humans are the race inhabiting Earth, the Third planet orbiting Sol. Humans and Helios share a close bond, and Helios are extremely protective of Earth, even so far as to dispatch one of their highest Lords, Serras, to defend it. Earth is beset by Gul many times, the most major incidences of which are described in the Solaris Series. Humans later give rise to the Changed, as well as a number of other races.
