The Interdimensional World is a limbo-like world between the human dimension and the Spirit World.
History[]
In this location, Lok Lambert was able to talk with his father Eathon Lambert, who was trapped in the Spirit World. Lok was also able to contact the spirit of Lord Casterwill. This allowed the young seeker to bond with Pendragon. The only known way to exit this world was with the help of Umbra, the legendary titan of dimensions. S2E48
