Dimensional Barrier

Overview
The Dimensional Barrier is a barrier maintained by the 'Cosmic Powers-That-Be' to separate the Demon World, God Realm, Shadow Realm, and Mortal Realm to make them impossible to breach. Certain exceptions are made for those of certain standing, or those who are marked as eligible for passage by someone with the authorization to allow it, but the barrier will first repel anyone who tries to travel through it, then - if one persists - one might find themselves badly burned (or vaporized) by the barrier.
