I was trying to get umbra (sword) at a low level, so I made her chase me into the imperial city. at one point she ran into a house in the waterfront district, and nothing happened. I went in and she'd killed the guard, and walked out. Then she ran, full speed, to the Temple District.

Once she got inside.. She stopped being hostile to anything. Now she's just wandering aimlessly around the Imperial City. Its been some time, and I don't think she's going to leave.
And that's it. if I try to attack her its a crime. Ive followed her but she just, well, wanders aimlessly.

So yeah. Wasn't expecting that.

Do you have a Frenzy spell?

don't think so >_> Im more amused by the situation than anything. I made a full save before even trying this (since it tends to result in me being dead) so yeah. I was just surprised it all happened like that.

You reformed her, she's had a change of heart and became a upstanding citizen again.

I've always wondered if I could redeem the poor thing. Get her to go back home to her people, and lay down that horrible sword (and the armor, if she's done with it) - I promise to dispose of them for her. After a little while...

This is pretty close to that outcome.

She always was. She went to hide in that ruin so as to stop hurting people. She's not hostile at all unless you attack her or challenge her.

I actually tried a low level assault on Umbra once, it took a lot arrows, poison, magic and a really good hiding spot to snipe her from. It took several tries but I eventually won----but boy was I hurting.
