You create a telepathic link between all creatures included as targets of the spell. Target creatures must be within the area of effect at the time that the spell is cast, but may then travel up to 1 mile per caster level distant and remain in contact with the thought pool. All participants of the spell can communicate to each other simultaneously to any number of other participants, keeping their telepathic communications private from participants whom they do not wish to include in their communication.
No two participants of this spell can be further than 1 mile per caster level apart from each other. Should this occur then the spell effect ends. A creature may prematurely end their participation in the thought pool at will.
