 Like the quori before them, the daelkyr tried to invade Eberron, but ultimately the Gatekeepers, a druidic sect dedicated to protecting the world from aberrations and outsiders, were able to sever the connection between Xoriat and Eberron.A few daelkyr were trapped in Khyber after the invasion was repelled, and they have been trying to get Xoriat coterminous with the material plane ever since.The daelkyr invasion was the main cause of the fall of the Dhakaan empire.
