The Interrealm is not so much a realm on its own, but a nexus point between all of the realms. The Interrealm has the appearance of a vast, seemingly endless castle room. Thousands of doors line the walls, with each door leading to a different realm. These doors are unlabeled, so unless one is familiar with the Interrealm’s layout, using it to travel to another realm can be dangerous. Opening the wrong door can lead to unpleasant or even deadly situations. Some doors are locked and sealed so that they nearly blend in with the walls. These are prison realms designed to hold some ancient evil or banished god. There are hidden portals to the Interrealm scattered across the Material Realm. Only those who have mastered certain forms of magic can find them.
