Divinity Original Sin: Nemesis Expansion

Aboard the prison ship headed to Fort Joy, an archdemon offers near limitless power to the prisoners. Taking up the offer ensures survivability but terms of the deal are vague. In a game where actions have consequences, Origins must outwit Adramahlihk herself or pay a steep price. This ever-escalating pact with an archdemon grants many boons, the cost of which may be worse than eternal damnation.
