Court of Madness

The faction, the Court of Madness is not introduced unless you have the Shivering Isles expansion pack. The leader of this faction is headed by Sheogorath, one of the Daedric Princes.

Noble Houses
The Court of Madness, similar to the Shivering Isles, is divided in two separate parts. Dementia and Mania are represented by their nobility. The Current Duke of Mania is Thadon and the Duchess of Dementia is Lady Syl. Each house has control of their Domains which is at the discretion of the Daedra Prince and each of them runs a part of New Sheoth. Bliss being for Mania and Crucible being for Dementia. The two sides troops are very distinct, the Dark Seducers being for the House of Dementia, and the Golden Saints being for the House of Mania.

Ranks
Consider your class when deciding whether to be the Duke/Duchess of Mania or the Duke/Duchess of Dementia. If your main mode combat is magic, then you should to be the Duke/Duchess of Mania as they have many gear that can upgrade your intelligence. Two examples are the Ring of Lordship and the Raiment of Arden-Sul. If you are more of the stealthy type, you should choose to be the Duke/Duchess of Dementia, as they have a ring of Lordship that makes you invisible. For people who are more of the warrior type, the best choice would be the Duke/Duchess of Dementia though it can go either way. You cannot be the Duke/Duchess of Mania and Dementia, thus making it impossible to earn the achievements (on the Xbox 360) for both ranks. In order to get both achievements, just save prior to deciding, or reload the closest save to that point in time.
