To Open the Gates
Githzerai came to Eberron as slaves to the daelkyr. When the Gatekeepers repelled the daelkyr invasion, many Gith threw off their shackles and escaped. Being from a far world, they keep mainly to themselves in small communities, but it is not unheard of for them to seek out a more exciting life of adventure.
