I think LC is working directly underneath the head in order to recreate the seeds of light project.
Dante keeps bringing up all the resources and personnel they have access to, and we know they have access to multiple singularities.
The sinner's rooms change to reflect their personality. Kinda like what happens in Keter in Lob Corp.
These hallways also look alot like Gebura, Chesed, and Hokma. Which are incidentally also connected on the tree of life.
In Dante's notes, he talks about how when a sinner distorts, its their EGO taking over them. This is more akin to floor resonances from the library than a normal distortion.
Also
Looks kinda familiar.

Just a guess but I bet that Dante isnt actually resurrecting anyone. I think he's just pulling in duplicates from a mirror world.
Also the Golden Bough is probably what creates the Qliphoth Containment. I also think they are pieces of Carmen.
notice how she doesn't have any legs.
