Remember this? [link]
Well, I guess this happened before or after that.
Brother Peanut and Stormtrooper Butler go way back. At age 14, they were both Cadian white shield guardsmen(essentially, conscripts). Their company was sent to the Cyrax system to help the Cyraxi PDF and IG against an ork incursion.
After one fateful battle, an Ork Nob brakes Butler's legs while Peanut manages to survive unscathed. Space Marines of the Immortal Lions of Caliban arrive soon after and drove away the orks. Peanut caught their attention and was recruited into their ranks while Butler had to wait for Cyraxi IG elements to come to him.
Long story short, Butler manages to get his legs working again and Peanut becomes a Space Marine. Together they fought against Warboss Oleg [link]
who reigns from his Mountain fortress.
I don't own warhammer stuff... Last note, I find skies and such difficult to 'complete'. I must find a way to get by this.
