On Cadia:
The tide of the battle in the tunnels began to swing again when Space Wolves reinforcements including Wulfen arrived while Celestine and her twin guardians assailed Abaddon directly.
It was then that the pylons began to activate, Trazyn and Cawl's modifications had been successful. The activation caused Celestine and the Legion of the Damned to become de-powered, Daemons and Psyker combatants to lose their power and causing the Immaterium to recede. This even began shrinking the Eye of Terror itself. Soon after this only those without Warp-modification are still standing unharmed, and it is in this setting that the traitor Astartes of the Black Legion gain the advantage. Just as Abaddon was about to finish the weakened Celestine, he was stopped by Inquisitor Greyfax who leads a counterattack of Cadian and Vostroyans.
Creed himself was able to arrive in the fray, briefing battling Abaddon himself and losing an arm in the process. Just as Abaddon was about to finish his hated adversary Creed, Celestine was able to get back on her feet and impale the Chaos Warmaster with her sword.
