The Fey, or Spirits as they are commonly referred to, remain some of the most common inhabitants of the Spirit World. Hence the name. The Spirits inhabit nearly every corner of the Spirit World.
Spirit of the Land
Places that have weak borders between the worlds are typically presided over by a Spirit of the Land, a fey who calls that area home and protects it from threats. They understand that the separation of worlds is vital for the future of the universe.
While elves are descendants of the fey, the eladrin remain more connected to their past than the others. Making their homes in the forests of the Spirit World, the eladrin remain more in touch with magic and nature than their counterparts.
