Realm Portals are portals that are located throughout the universe that allows travel between realms.
Realm Portals come in different shapes and sizes. Their color is determined by where the portal leads (a red portal would be leading to the Hell Realm and a white portal would lead to the Heaven Realm).
Realm portals are located across the universe, however they are rare and hard to come by. Going through a realm portal would cause you to leave out of the corresponding realm portal.
