*You find Baal, and a contingent of his finest: The Cartographers, a group of immensely powerful magic users with great intel gathering and (surprise surprise) an immensely great geo-magic. There's also another guy there, seemingly a medium. Baal is easily the tallest of the group by a whole three feet, and on top of this wields a huge sword-the Baal Greatsword. That same inscription comes up.*

*Baal eyes you up, and the Cartographers seem prepared to kill you if you get violent.*

Mediator: You stand before the great Tyrant Overlord Baal, Incarnate of Conquest since before reality itself...For what reason?
