Following a tradition that dates back into the dark ages, an abbey's muniment room - where the documents are kept - is located close to the calefactory, where the power generators are. This probably goes back to a pre-industrial era when the calefactory was the only heated place in monasteries, and documents needed to be kept close to that room so they would not get damp and moldy.
The historical archives of the Order are also located near a site where the power generators are. Mostly fission reactors, creating enough excess heat to melt some of the ice on top of the site. The site itself is mostly undergound, to protect it from orbital attacks. It looks like a chasm, an immense hole in the ground, and that is why people refer to it as "the pit." A dark place in a dark world.
It appears to me that it also houses a kind of command center and fleet hangars. The security is tight, and I am constantly tracked. I'm only allowed in some restricted area. But I could finally start working - I've installed myself in the reading room and I have found a helpful assistant archivist. Helpful, but like everyone else here, not very chatty.
