Spirit Plane

The Spirit Plane is a plane of existence from which Summoning energy can be used to summon creatures.

Very little is known of the Spirit Plane. According to the druid Pikkupstix, it is here that spirits freely wander. When some one summons a monster, one of these spirits manifests itself in Gielinor as that creature.

Whether or not the Spirit Plane is a seperate world, or universe, from Gielinor is unknown. It may be another "part" of Gielinor, although it is not a geographic location on the planet.
