As far as Shrine details goes there isn't much on them. They have appeared a few times in different editions of the codex and have appeared in Valdor Warzone Book (hence my first choice for Iyanden), then on Lexicanum they mention that the Sable Helm Shrine battled the Orks of Waaagh! Greksh on Chogoth Delta and ended up slaughtering the Greenskins. So they seem pretty badass. So here they are in their full squad glory.
Now with so little background on them that leaves it open for me build off. So on this page I will write my own history for this Shrine and build off it as I manage to get some games in:
