Senjak, along Dorotea, 3 archers and 2 bandits ambush the party when you first travel to the Nashkel Mines area, as a part of Dorn Il-Khan companion quest. Although she attacks Dorn, he will not die in this encounter, staying at the near death state with the last pipe on his health bar. The encounter takes place before you actually reach the Nashkel Mines area, making it possibly the only non-random encounter to occur in a transition area.
