Available: After the College Quest: Under Saarthal .
Locate Brelyna inside the College and speak to her. After some chat, she asks you for help on her magic. You just KNOW this isn't going to end well, but we're nice... Agree to volunteer and all the screen will turn green...
If you say what's in it for you, she gives you an enchanted necklace. But even if you don't, at the end you'll still get an enchanted necklace .
She tells you that you shouldn't worry since it should wear off in a little while. Yeah right. Wait for the effects to wear off, go run around the College, start another Radiant Quest, I don't know. Do whatever you want until you can see clearly once again. Once you can, return to Brelyna and agree to volunteer once more.
She now casts a spell on you that transforms you into several animals. Ha! After changing several times, she's not convinced that her spell works (I wonder why) and decides to stop. She then thanks you for helping her out and, if you want her to, will follow you in your adventures as she can now be your companion.
