a friend of mine today was talking that some guy at the local game joint where we play warhammer said that there is or was a chapter of loyal space marines who used ork weapons and looted stuff etc. on a regular basis, also that there was a chapter master who actualy replaced his own hand with a hand of a warboss.

i find all this very unlikely and i can't find anything on this matter anywhere, so this is my last try at the comunity brain (yes hive mind lol), have any of you heard of such a thing or is this just something made up?
