Forerunner (Dungeons & Dragons)

In the Dungeons & Dragons role-playing game, the Forerunners were the ancestors of the Githyanki and the Githzerai, who were enslaved and altered by the Illithids. Remnants of the Forerunner rootstock, the descendants of those thralls that never managed to escape the illithids, still exist on Penumbra, the abandonned capital world of the vast illithid empire. They are all that remains of their race from before the rebellion lead by Gith. Having reverted to barbarisms after the fall of the illithid empire, they retain little knowledge of their own past.
