If you're looking for more information on the Coirnav Progression Server you can check out the Coirnav FAQ!
Already curious as to when the next Progression Server unlock will be? You can use the in-game events calendar to check! The events calendar can be found under the EQ Button's "Alerts" sub-menu, or by using the "/calendar" command.
Special note: Some NPCs or other game features may require up to an hour or so to appear correctly in-game after this content unlocks.
Shoot for the moon, adventurers!
