The Key Keepers

The Key Keepers, or keepers of the keys, were the guardians of the old teleportation spells and portals, and resided in New Kumbaran.

After the collapse of all relations with the Dragonborn, the Key Keepers were instructed by the Shield council to close and bar all of the portals across Yar-zun as the portals might be used by the Dragonborn.

The Key Keepers constructed the Osarus' Hall of Doors.

Players can send for them and they’ll come to Umbara via their portals.
