The three of us stepped out of the Skingrad Western Gate and somebody attacked somebody else before I could see who or what was happening. The first victim was Tutius sixtus's horse, killed by a black-robed and black-hooded supplier, who I figured at the time was the original aggressor and who was killed by someone else. However the fight continued, taking out Tilmo and Davide Surille (who I resurrected just in case I decided to help out Glarthir.) Several more passing natives joined the fray, including the other archery trainer, who ran away after a while and the shepherd whose body wasn't in sight at the end, so I think also made it. (No sheep were harmed either.)
I found Stoker and Vilja had cornered a Skingrad Guard and stayed the heck out of it, not wanting to end up with a bounty because one of the three was a bad shot. The inevitable death of the guard did not end the fight, however. A couple of passing adventurers, and travelers as well as Tamika were in fast and furious battle with a harmless looking Dunmer, labelled "Traveler", who was attacked by both my companions as soon as the guard went to his reward.
Then I realized that the Dunmer was yelling things like, "Your blood, I must drink your blood!" and hissing. As far as I can tell he was a vampire who'd been minding his own business when the necromancer supplier (he had 15 skulls on him so I figure he couldn't have been anything else) attacked somebody. I finished the vampire off and collected much loot from the bodies.
But mostly I'd love to know what the heck it was all about. Neither Vilja nor Stoker was forthcoming. :unsure2:
