Terehn
The terehn are Zirconya's immortals. This includes the Sages, the Olintor and the keepers of the chambers like Keiren Kai and Lockesith Syn. Anyone dealing directly under The Highest Power's will. They can be killed but they do not age which has earned them the name "terehn" or "Time Spirits." They are not considered the living, nor the dead.
The elders are not of the terehn. They live long because they are wizards, but they likely will not live passed 1000.
