The wizard Arena meets up with me every so often, I cannot get rid of her. There is a quest in her name where I have to fight for and give her the mask of Vokun. I can't remember this quest and I cannot remember her. I am actually wearing the mask and her dialogue doesn't recognise this.

So I cannot give her the mask and I cannot get rid of her -- any ideas anyone ?

Uh, you mean "http://www.uesp.net/wiki/Skyrim:A_Scroll_For_Anska"? She wants the scroll, nothing else. Check the last paragraph of the detailed walk-through.

Edit: Say, wait a minute... it's déjà vu all over again!

Well spotted, I just flew this again to try to get more replies. I've never been followed before by a wizard or NPC, that's the issue I was trying to bottom out.

Well, what are you waiting for? Give her the scroll already! Her supper's gettin' cold.

Unless you want her to keep following you, that is. I don't remember her being worth much as a "follower" in that quest, even as a distraction.

She can get very psychotic when she starts using Fireball.
