Outsiders are creatures not native to the material plane of Eberron. Outsiders can come from any of the other planes of Eberron, and include creatures and races such as archons, demons, devils, mephits, and quori. Other creatures, such as daelkyr and elementals can be considered outsiders, but usually fall under another category, such as Aberrations or Elementals, respectively.
