What the actual Hell is going on in my Skyrim today? I've had plenty of time so I've been on a bit of an epic walk, Whiterun to Dragontooth Crater, no fast travelling. Just past the western watchtower, I was attacked by a Nord; not a bandit, or an assassin - just "Nord" on the HUD. Odd, I thought, but I continued on my way. Down the road a while, I was attacked by a Khajiit - again, listed on screen as just "Khajiit", and no Assassin's Notes or anything in his inventory. What? OK...a little later still, an Orc had a go at me. Then an Argonian, and then a fellow Breton. Then
A VIGILANT OF STENDARR.
What in the Bejaysus is happening? Has the whole of Tamriel turned against me? Have I unknowingly passed some threshold in the game after which this is supposed to happen?
