She attacked me for no reason. I walked up to her and said hello and then she starts attacking me.
I just slit her throat from behind, nice and clean.
Toss the carcass in the nearby river and one has a neat little resting place.
The letter in the basement, it says a girl named helgi was invited to join a witches coven and helgi was the girl who died in the house the burned down in mortal
The Helgi referred to in the note is probably the old lady in Riverwood. Sven's mother, first house on the right as you enter coming from the west.
Anise's cabin is even nicer, because just east of it there is an event trigger location. It's just east of the big fallen tree, about halfway to Riverwood, and every day or two there are new people/events.
I've no idea wether the chests and containers in this cabin are resetting or not. I've heard that only the Apothecary Satchel is non-resetting from this wikia, but I've also heard that all containers are non-resetting in the cabin from other sources. I'm on track to confirming or proving this wrong right now.
Low-level characters looking for a home should note that killing Anise may cause an NPC from the Hagraven faction to send a gang of three thugs to attack you as revenge. This fight can be a bit of a beast for low-level characters.
If you are a mage or know calm, you can cast it on her. Then she goes kinda dumb and says "It's so nice to have visitors." It's kinda cute .
P.S. when it wears off she gets mad again.
