|“||There is no one smarter than the Engineer, and nothing is more deadly than his snares!||”|
The Engineer, also known as the betrayed one, is an ancient spirit. In Divinity II: Flames of Vengeance he is summoned by a pair of monks, Abbott and Charles, in an effort to recover an extremely rare tome of sorcery. When freed, the Engineer possessed the body of Charles and initiated the plague of walking dead that threatens the city of Aleroth. The Engineer is assisted by a troll named Skulk, who calls him, "the greatest intellect in Rivellon." He cannot be mindread.
For the quests Dead Rising and Nericon's Wrath, the Dragon Knight is tasked with finding and ending the source of the undead - The Engineer. When he is confronted in Source Square, pull the four levers in the district before attacking him. When killed, a chest spawns nearby that contains the Engineer's Sword for Clue IV of the plot quest To Find a Wizard. Killing him also rewards the "Sharp as a Steel Trap" achievement.
