Welcome to our guide to Ktisis Hyperboreia, the fourth dungeon of Endwalker. This guide aims to prepare players for the dungeon so they will know what to expect, with simple mechanic instructions and notes on what to watch out for.



The most extensive facility in Elpis, Ktisis Hyperboreia is a sprawling complex of magically simulated environs. Concepts awaiting evaluation are brought here for the last stages of observation, and, upon meeting the appropriate criteria, are finally released into the world at large. Determined not to surrender Meteion, it is within this facility that Hermes has taken refuge, and you and your companions must find and confront him if you are to shed light upon the truth of the Final Days.


Unlock Requirements

Ktisis Hyperboreia can be unlocked at level 87 during the main scenario quest "Caging the Messenger." It is the fourth dungeon players will encounter in Endwalker and is located in Elpis. Players above level 88 will be level synced to level 87 when entering, and there is a minimum item level restriction of 515 to enter.
