Walkthrough
First you talk to Nazir and tell him the Night Mother has spoken and the contract is still on. Then you go to talk to Amaund Motierre, he will tell you that the Emperor is on the Katariah. You have to go underwater and climb up the chain that is holding the anchor, once you're on board there will be several sailors and Pentius Oculatus Agents.

Continue up the stairs and go south, there will be a ladder to the main deck, to the right of the ladder is the captain's cabin. Captain Avidius drops Gold (4) Katariah Master Key, Potion of Minor Healing, Clothes, Boots and an Imperial sword. Now you must go the opposite direction, and go towards the door at the door, locked (expert) and use the key. Upon entering there is a room to your right with two Pentius Oculatus Agents, there is smoke rising from the floor, continue up the stairs and you will see the Emperor's Quarters, unlock with the master key. You may also get the key by killing the lieutenant who is in the room directly below the Emperor.

Emperor Titus Mede II will start talking to you upon entry, accepting his death, stating this is our destiny, he will ask you a favor, to kill whoever assigned the contract "Amaund Motierre". then you enter The Bannered Mare in Whiterun to talk to Amaund Motierre, he tells you the money is in the dead drop in the cave where you first met (Optional kill Amaund Motierre) If you chose to kill him and get his many valuble gems, he will say with his last words "We...had a deal" and die. (climbing up on the table next to him will allow a stealth backstab that will kill him without calling the guards)Then travel to Volunruud, to collect your dead-drop award inside an urn "Gold (20000)". You must then talk to Nazir in the Dawnstar Sanctuary, you can tell him Motierre gave you 20,000 gold 10,000 (lie) or 5,000 (lie).

Loot
In front of Emperor Titus Mede II there is a book "Brother of Darkness" which tells some history of The Dark Brotherhood, there is also a map in front of him, the same as the "cloth physical map" that came with the game free of charge, if you pre-ordered.
