Trellheim - The Borr Barony
Asmodian Gate Medallion
The Asmodian Gate Medallion is a minor artifact, that has been broken up into 7 pieces and then the individual pieces hidden. When completely assembled, the medallion is reported to allow Asmodeus and any of his followers to travel freely between any plane of existence. It is even rumored to allow access to Bags of Holding and Portable Holes, as long as they are within a few hundred yards of the medallion.
It is also known to provide the bearer with various abiities and benefits, depending on which and how many of the pieces they possess.
The only abilities of the pieces known for sure are for the 2 pieces which form the outer frame for the medallion. When combined, they act as a master control for any functioning gates nearby.
