Senjak

Senjak and Dorotea, along with 3 Archers and 2 Bandits, ambush the party when you first travel to the Nashkel Mines area. You have been thrust into a quest, of sorts: Dorn Il-Khan (quest). "We should kill that one last, Senjak. Such good manners."

- Dorotea 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.

The 3 Archers may also be the only NPCs of their kind in the game, but they drop loot quite distinct from that of bandits, for example, and the dialog identifies them as "Archer" when they die.
