[@Tyki]He is on Tor-6 by pure fluke the Grey Knights will not be able to reach Tor-6 because it's an entirely different universe. And Valentus has had little to no rest since he arrived, with Mithias now a champion of Chaos and Rex in an overpowered state of which he has never been before, Vale is screwed especially if Luigi and his body guards help Rex and Mithias. Vale is strong yes but he is not indestructible. And you have other characters and there are other worlds, use them to progress your own story.
