If you left Cicero alive, you will meet him upon EXITING the Dawnstar Sanctuary. From here on in he’ll be just another brother. However, you can command him to follow you and he will. You’re BFF’s now, after all!
Time to re-decorate our new place. With the 20,000 gold that we got from Amaund we can go talk to Delvin to procure new features to our Sanctuary. Head to the ratway and then on to the flagon to meet Delvin. Talk to him and tell him you need new furnishings.
Here’s the furnishings you can buy from Delvin:
New banners (1,000 Gold): Pretty self-explanatory, no need for me to explain this, right?
Poisoner’s nook (5,000 Gold): Add’s in an alchemy station, as well as a small little garden full of plants. Pretty nice.
? Torture chamber (5,000 Gold): This more or less give you four prisoners in your torture room. As a special note, you can interrogate EACH of them to receive FOUR different miscellaneous quests entitled " Take the hidden treasure ". We’ll handle those quests a bit later on…
Secret entrance (5,000 Gold): This adds a secret entrance to the Sanctuary in the main room (investigate the stained glass to go right outside). You’ll be taken to a spot just south of Dawnstar . Pretty neat.
Master bedroom (3,000 Gold): Gives your bedroom a makeover. Includes a chest, big bed, a mannequin (to display armor on) and a special set of gloves called TUMBLERBANE GLOVES , which make lockpicking 20% easier . A nice buy.
Once you buy all available upgrades (and oddly enough you have to talk to Delvin again) this quest will be complete. It is not followed by anything. Go check out your new Sanctuary and check it out. If you add up the price of everything I’m sure you noticed that it comes out to 19,000 Gold, so you can easily afford it all with the 20,000 that Amaund gave you.
From here; the DARK BROTHERHOOD QUESTLINE is essentially complete. You can do the re-occuring quest " The Dark Brotherhood Forever ", and finish up the few miscellaneous quests that we’ve received through the course of this questline (all of which are documented below). But the most important thing is to have fun, Brother.
