Portal Beacon

When this spell is cast, a portal designated by the caster projects a mental call to up to six intelligent beings chosen by the caster. The beings must be known to the caster, but need not be present at the time of casting. Those selected always know the direction and distance to the portal as long as they remain on one of the two planes it connects. Thus, the spell's call has a virtually unlimited range.

A planewalker wizard designed portal beacon so that adventurers would never lose track of their gate home. The trick is leaving and returning to the gate before the spell's duration ends.
