The universe consists of five realms. Our reality exists upon the outermost or top layer, known as the Fifth Realm. Going “down” from there, there are two intermediary realms. The Fourth Realm/Umbral Realm is a hazy reflection of reality, but absent of naturally occurring living beings. The Third Realm/The Fold, is a membrane that divides the higher realms from those below. It can be traversed, but there is little to no physical structure to orient oneself. The Second Realm/Spirit Realm is the source of Flux Essence. Impressions or shadows of living beings can be seen here, but there is no physical characteristics. The First Realm is known as the Hub, see: The Hub/Hubspace.
