You grew up as a member of the Sanctum Universum. You gain access to a special chest full of items in the Sanctum Universum in New Atlantis, but lose access to the House of the Enlightened chest. (Can’t be combined with any other religion trait.)
Where to Find the Sanctum Universum Chest
The chest will be in the Sanctum Universum in New Atlantis, which you can find by going to any train station and then taking it to the MAST District (Image 1). From there, simply go up the ramp, turn left, and look for the circular, golden building (Image 2). Once you reach the building, head inside and look to your left, where you will see a Chest just below some glass outside of an office (Image 3).
What is in the Sanctum Universum Chest
Inside the Sanctum Universum chest, you will find the following:
Sanctum Universum, Vol 1
Sanctum Universum, Vol 2
Sanctum Universum, Vol 3
Med Pack (5)
Boom Pop! Rhubarb
Keeper Aquilus often wanders around the Sanctum, and you can approach him for some unique dialog, where you tell him about your Universal faith, as indicated by the “I’ve always found wisdom in the Sanctum Universum.” dialog option (Image 3). Doing so will allow you to speak openly about your faith, though you made need to do some reading of “Among the Grav Jumps,” which you can find on the podium in the Sanctum (Image 4).
When you return to Keeper Aquilus after having read the book, there will be more to discuss. As well, you can remove your “Raised Universal” trait by talking with Aquilus, and selecting two options labelled “Remove Raised Universal,” where you will voluntarily leave the organization and, thus, lose the trait.
