There's nothing noblebright about what's currently happening in the 40k universe though.
The Lion and Russ coming back to form their own independent Imperial factions as foils to Guilliman.
It would definitely add some much needed pathos in this noblebright universe.
Besides, they already copied the Ruinstorm from the Heresy, they might as well do another version of Imperium Secundus.
Alright I gotta ask. Are you actually serious with this one or is that just a bad trolling attempt?
