{Loading screen} {Gameplay} The Guardian heads into Firebase Rubicon. After traveling through the tunnels, the Guardian emerges into the Rubicon Wastes. On the far side of the area, legions of Cabal are seen fighting a Wolf Walker. With the assistance of the Cabal group, the Guardian eliminates the Walker. Mission ends.
 * VARIKS, THE LOYAL: House Wolves seeks to claim territory, as Fallen always do. Brute force, no mercy. Cabal are soldiers. Trained for war. Very good at war. This time, I think Skolas' crew have met their match.
 * VARIKS: Hmm...weapons fire on far side of base. Intense...very intense.
 * PETRA VENJ: Variks, have you had any luck finding their new Kell...if they even have one?
 * VARIKS: No. Fallen Houses do not...we do not handle loss of leaders well. For Wolves to be moving, organized, someone must...lead.
 * PETRA: A Walker!? Where do they find these things? Guardian, stay out of the crossfire. Good luck!
 * VARIKS: (proudly) Walker down! Cabal in retreat! Expect no less from you, Guardian. Variks forming...theory. Will continue search for leader of House Wolves, yes.
