📋 About This Mod

Far on the eastern side of the commonwealth you come across a mysterious building that seems to beckon you inside. Once you enter a Librarian tasks you with finding something very precious to her. Will you turn down her request? or go on a journey across space and time?

This mod contains two quests, a vault and something a little bizarre.

Helpful Mod Notes:

  • []The mod is level based which means enemies and loot will change in relation to what your current level is.

    []This is a standalone story and both quests do not effect the original story line in anyway

    []To start your quest visit the Akashic Library. A map marker has been added to your pipboy on the eastern side of the commonwealth (near Salem).

    []There are three NPC's in the game, two of which are voice acted. The third NPC "Casey Miller" is voiced using a text to speech program.

    []Reward wise, there is loot spread through out the vault and a peace of power armour.

    []The story of what happened to the Vault is mostly told through the many terminal entries so you may wish to read them from time to time.

    []You will need to speak to the Casey Miller, an  NPC who is upstairs in the Library to get the key that unlocks the elevator inside the Vault.

    []None of the Fallout 4 DLC's are required for the mod. Just the base game.

    Where are all the damn keys? (Spoilers)

    I wasn't going to put this here as i think there's fun to be had in finding the keys for yourself but for people who really aren't interested in the search the locations to the keys are below.

    1. Depot Key = Located at Vault Reception on the desk just underneath the terminal.

    2. Atrium Key = Located directly in front of the Atrium door, on the floor.

    3. Overseer's Office Key = Located in the Residental Area > Nursery > on the sofa beside the two skelitons.

    4. Maintance Key = On the overseer desk just underneith the terminal

    5. Past vault nursey key = In the cafteteria back in the vault of the past.

    6. Overseer Terminal Passcode = In the Overseer's office back in the past vault

    7. Elevator Terminal Passcode = This is a passcode given to you by the Casey Miller NPC back in the Library when you accept the quest.
