As for the others:
- Beitild was most probably killed by either her ex-husband's order or by that of one of her own workers, whom she abused in order to one-up her ex's mining business.
- The hit on Ennodius Papius was most likely ordered by one of the millers he once worked with at Anga's Mill, in order to ensure that he wouldn't give up his reclusive lifestyle and return to work, wresting control of the mill from Aeri. At a guess, I'd have to say Kodrir did it, as he seems so suspicious of strangers and unfriendly. Maybe he's been playing mind games with Ennodius all along and is going to be after Aeri next in his bid for ownership of the mill.
- I've at least got a pretty good idea of who didn't want Lurbuk killed.
Jonna, the keeper of the inn in which he lives doesn't seem to mind him too terribly.
- Hern was most likely killed on the orders of a traveler who passed through the area once and had a bad experience with the vampires in the mill. Or maybe it was even someone in Falkreath. As he couldn't trust the Legion, Stormcloaks or the incompetent local authorities to take out the threat, the Dark Brotherhood may have been the most logical choice for once.
- Deekus' contract was probably made by someone who wanted the treasures he'd scavenged all for himself. Or maybe it was someone who was trying to keep a secret buried beneath the waves of the Sea of Ghosts.
- As for Ma'randru-jo...hard to say. A lot of people don't take kindly to Khajiits and if he cheated someone once on a sale, who can say that the one on the losing end of the bargain wouldn't want to kill him?
- Anoriath - Olfina's a surprisingly good theory. 0.0
- Agnis' death was probably ordered by the men she's been cleaning up after, as evidenced in a
couple of
letters. After how long she's been stubbornly living in Fort Greymoor, there was literally no other way to toss her out.
- The reason for Maluril's death was probably the bandits with whom he'd aligned himself. Or some of them at least. Maybe they wanted more of a share of Mzinchaleft's loot but were too afraid of his magic power and the opinions of the other half of the group to take him out on their own.
- Maybe Helvard's death was the result of a remnant of the bandits Jarl Siddgeir had murdered getting their revenge on him.
- Safia's a pirate. What else is there to say?
