The Planar Tuner

The great dwarven rune smith Modlet Brasslance had a goal of creating an item that would let one tune themselves or another creature to a plane with a certain frequency and bring that creature there. The Planar Tuner is said to have been able to do just that, forcing objects or people to be banished to other planes. It was set to arrive in the Hilt for study, but the ship never arrived.
