ya know my primark that guy needs to accept his blade back so I can be a dark angel again and not The Fallen !
I think he's sleeping at the moment, actually. Let me use my runes and check. Yes, I see a- a rock? A rock of some sort, floating in space? Wait no, that's not - ah! Apparently the humans have built a fortress on it! Silly creatures, those Mon'Keigh. Whatever the case, knock on their door, and ask them about the matter. I'm sure they'll direct you to the proper direction. (And besides, wasn't it the Corpse-Seer you were supposed to return that blade to, not your Primarch?)
With this great teleporting system that Tzeentch gave me ill flash in there and give that bastard this sword...
