So in the new teaser trailer Guilliman claims that they have bred new warriors for this dark age. They are the truest heirs to the primarchs legacies and their appear to be thousands of blue tubes with their experiments in them. Apparently they will reinforce every chapter with these new warriors.
I just wanted to ask if anyone has any idea what these reinforcements will be. I have been trying to come up with some sort of theory but i am honestly baffled and thought I would see if anyone else has come up with anything?
Cheers
