Korthia, City of Secrets is an ancient realm of the Shadowlands that was long lost in the In-Between before being dragged into the Maw by the chains of the Jailer. Similar to Oribos, Korthia is inhabited by attendants but also its own strange creatures, and the area contains many mysteries and secrets of the First Ones. The Jailer is searching for these secrets in the hopes of finding the key to fulfill his twisted vision for the Shadowlands. Korthia was hidden away in the In-Between to hide things that the races of the Shadowlands didn't want people like the Jailer to find.
Korthia was controlled by the Fatescribe Roh-Kalo and an Archivist who kept track of the records. The Archivist, currently Archivist Roh-Suir, wields a Lodestaff capable of locating any artifact, usually powered by the Netherstar. Korthia being stolen by the Jailer has torn the very fabric of the Shadowlands. Before the Primus was taken by the Jailer, he had entrusted his sigil to Korthia.
