Duke Dementia, Shivering Isles

Reached Duke of Dementia Rank in the Court of Madness   
Warning: Make a new save now if you want to get both Duke of Dementia and Duke Mania in one playthrough.

Speak to Sheogorath and chose to become the Duke of Dementia. He will instruct you to kill Syl and take her heart. Speak with Anya Herrick and Kithlan who work closely with the Duchess. They will reveal some secrets about Syl and how you can reach her. You'll now need to follow Syl through a network of tunnels. When you find her, kill her and search her body. Take the heart and return to the Sacellum Arden-Sul to complete the ritual. You'll now become the Duke of Dementia.

Refer to Ritual of Dementia for more information.

Which one is best to use on playthrough, or does it not make much of a difference to the story?

@#3 same here! And now I have to play the whole of shivering isles again just to get the other duke achievement...... It's taken me 6years to be bothered to do so! And that's only because I just finished skyrim 1000/1000!
