|1||My name is Lachdanan, and I am cursed. Once the captain of King Leoric's army, I lived only to honor my land and my king. No man has a greater love for his king than I had for mine, even as I drove my blade through his dark and corrupted heart.||The Legacy of Cain|
|2||It was Lazarus - of that I am certain. He alone had the king's ear and whispered dark and evil magics into it, instilling the notion of an imminent attack by Westmarch. Afraid to speak against the archbishop, the councillors nodded their empty heads in agreement and sent us off to die.||The Legacy of Cain|
|3||When we returned from our horrific defeat in Westmarch, my beloved king lost all pertense of sanity. He seethed with rage, spitting curses upon us as traitors. With great sorrow I ran him through.||The Legacy of Cain|
|4||I will forever live in anguish for my last attempt to honor my king. As we lay him to rest in his burial chamber, he manifested as a hideous skeletal demon. Gorash and my other knights were overcome at once, but I fought on.||The Legacy of Cain|
|5||And now I wander, cursed by my once-beloved king. Evil gnaws at my bones, and I cannot risk putting my beloved Tristram in danger should I fail to contain that which tears at me. I must venture down into the labyrinth to die alone.||The Legacy of Cain|
