In life, Leon was a devout priest of Stendarr. But, when Nord invaders attacked Westtry, his faith was shaken and it pushed him to turn to Molag Bal for a solution. In doing this, he cursed the town himself, dooming the inhabitants to relive the invasion for eternity.
Leon made a pact with Molag Bal that placed a curse upon Westtry. The final twist was when Molag Bal turned Leon's wife and the captain of the guard, Rosalind Milielle, into a vengeful shade. She may hold the key to ending this curse.
