The Traitors gather in the new timed event!

"All of you keep underestimating me!"
– Perturabo

The Warmaster rallies his forces before the final push for Terra. Tensions run high with the promised victory on the horizon, and the war council quickly devolves into a fearsome fight between the traitor Primarchs as old grudges rise to the surface.

Choose one of the traitor Primarchs and prove that might makes right! Will the Warmaster be able to retain control of his erstwhile brothers and lead them to Terra?
