Help identifying

[Deklend]

ok, I just need a little help identifying if a couple of guys who randomly attacked me are from a mod or if it's vanilla to the Dawnguard DLC. I'm doing a vampire playthrough which is something I don't normally do, but wanted to see the quests from that side of things when I'm randomly attacked by a vampire NPC named Vigilant Talwin and one with a generic Hired Assassin name. When the one starts talking though it's named Tolan instead of Talwin, but by all accounts Vigilant Tolan is dead in Frostmere and not a vampire. Here's a screenshot of the NPC:

and one of the contract on the Hired Assassin's body:

Vigilant Talwin himself teleports out when he hits 0 health, and the contract itself doesnt start a quest or the like.

 

And my load order for S's and G's:

Vigilant hunters are added by the "Better Vampires" mod. You can turn it off, and even customize it by choosing how many of them will attack you; solo hunters or several at once. The hunters (the hired assassins excluded) are always 5-10 levels above your skills and carry silver weapons, so you might want to set it to solo at lower levels when you don't have a follower. I'm level 101 now (SkyRe) and they are level 112, so they're not much of a challenge anymore, so I set the mod to Triad hunters, I think... whichever is the highest possible option.

he appeared to me a few seconds ago (alone). it's strange, because he teleports out before he dies as well as the wrong name. that's different from the "better vampire" hunters.

He runs when his health reaches low, after he does this about 4 time you can kill him.
