Upd: no any unusual story quests, even those that appear in the job list.

2. I do not remember where we had met the witch, who asked me to free her and kill the other hagraven. The award is also like a staff.

3.If, after the assignment on the peak of the wind (well, not remember the name. The first ruins with the Golden claw), if you walk along the upper Bank of the river, you can meet a girl escaped from the bandits located in one tower. Finding the tower meet there the man looking for his kidnapped wife
