So I've been playing an Orc who will join the dark brotherhood but his goal is to one day start an Orcish branch within the Dark Brotherhood that he will lead.
My question is if anyone knows of any Orcish ties within the brotherhood through lore.
Also, is it possible to have an initiate as an Orc, or an Orc followers that will stay by my side as an Assissin (has a tolerance for all crime)

All I know about is Gogron gro-bolmog and how awesome he was.

Probably a better question for the lore forum.

There are no ties as far as i know, for the most part they are completely unrelated. There are a couple orcs in the Orc Strongholds that will be followers, but none that are stealthy in any way.

Durak from the dawnguard is pretty good for such things I found.

Well the more important question for me is the one that affects gameplay. (Orc follower/initiate)

Do you know if the orcs in the stronghold are tolerant to all crimes?

Durak (an Orc follower) from dg doesn't seem to care what my character does.
