Quest 5: Understanding Madness

Fast travel to New Sheoth Palace and speak to Sheogorath to receive the Summon Haskill lesser power. Summon Haskill once, then speak to Sheogorath and summon him again. With that over done, ask Sheogorath about Jyggalag and the Knights of Order to learn more. After that, Sheogorath will order you to converse with both the Duchess of Dementia and the Duke of Mania.

There are doors to the left and right of Sheogorath's throne. The door on the right leads to the House of Dementia and the door on the left to the House of Mania. At this point, two new quests, 'Addiction' and the 'The Lady of Paranoia,' will be added to your journal. These two quests can be completed in whichever order you please.

Speak to the Duke of Mania and the Duchess of Dementia and accept their quests.

Once you have completed both 'Addiction' and 'The Lady of Paranoia,' return to Sheogorath for further briefing.
