Ithulde the magician makes you an offer - return 'The Rituals of the Ancients' book to her and she will pay more than Senera.
- Quest starts when you speak to Ithulde and ask her to open the teleport.
- Unfortunately there's no way to avoid getting this quest. So in the end one of two will be failed.
- If you return book to Ithulde, you will fail the main (Senera's) quest and lose fame.
