Who is Nemesis?
So i have a theory.
I think Nemesis is from the Prime universe, and i think i know where they originated.
We know that in 1218, Carrie shut down Die Glocke in the past before it could come fully online. But in Prime, as far as we know, that did not happen.
Die Glocke is a techthulu, and if its online and functioning in the Prime universe, it has access to the entire Multiverse. I believe this is the driver behind the Nemesis organization.
There are a few hints that seem to tie Nemesis to the Nazi regime, which is the when that Die Glocke originated. Their glyphs are runic in shape and impression, and Stuart LIghtner used the phrase 'Hail Nemesis' recently on one of the leaked Dunraven videos. Ok this is thin but the picture i'm seeing fits so far. The things they are capable of seem to suggest an entity like a Thulu is working with them, working for them or perhaps control
