Yeah, she is a badass, and is even badder than ever!
Acadian: yes that is Dark Brotherhood stuff going on, but I played around with the order of how things work, so that Mycharonna comes back from the (un)dead.

When I moved her game from Xbox to PC, she is supposed to have been killed by Titus Mede II, and in the process of this she gained all sorts of cool powers that aren't possible on Xbox. For instance, undead and some conjurers now see her as an ally. A lot of animals no longer attack her. Unenchanted weapons don't harm her nearly as much, etc.
And then I also added a really well-done mod called Better Vampires. All sorts of neat features in that one. Sun damage, the ability to have Dawnguard in her game, yet she still gets hated when she gets to Stage 4 (the most powerful stage of vampirism). A bunch of neat spells, like "Invoke Fog" and 'Call Creature'. Etc. Etc...
I will post some pictures that go along with Bjorn's latest update, in Markarth.
Chillin'Phishin'Fightin'Sparky Bzzt! (....note, Calcelmo's Dwemer Museum has this weird mechanical spider which will become the best friend of whoever activates it. So Bjorn is standing in the background, while one of the museum's soldiers deals with that spider!
This part of the quest was interesting because since Bjorn was dressed like a guard, most of the other guards in the museum didn't bug him (thanks to me putting him into some guard factions).
