Archives is a new addition to Assassin's Creed Odyssey: Judgment of Atlantis. These are sites where you can find many elements giving you knowledge of Isu. Thus, you will quickly develop your character.
Archive of Hebe is located in the western part of Oikos of Atlantis.
The entrance to the archive is at the bottom of the building. You can notice them easily thanks to the door's golden glow.
At the start, destroy the torch located on the right side of the room.
The second torch is hidden on the left, behind the shelves.
Eliminate all the enemies before you start exploring the location.
A chest with knowledge points is on the left. The hologram above it glows blue so you won't miss it.
A small room is at the end of the location. Inside, you will find a tablet.
