Skyrim Mod:A Tale of Blood and Snow/Syncope Sanctuary
Syncope Sanctuary is a ruined farmhouse just outside of Dawnstar, on the coastline to the north-west. The dilapidated building features an odd bed, with a caged skull resting on its pillow, and several Eyes of Sabre Cats as well as Watcher's Eyes can be looted on the bed and next to it. There is also a Black Soul Gem.
The bed actually functions as a door allowing to access a new player home. You need a special key, which is received by courier after concluding the quest line for your faction: The Mercy of Stendarr for Ciirta's Vigilants, Master of the Brood for the Cronvangr Clan, or Might of the Quarra for the Quarra Clan. If you sided with the Vigilants, you receive a Letter from Ciirta Antabolis explaining they found the key in the Stormcaller Cave but it did not seem to fit any of the lock in there. You are tasked to find out what it opens and deal with whatever threat might be revealed. If you sided with either of the vampire clans, however, the letter is presented as A Small Gift from your old friend Viatrix Caerellia who explains that since she is coming back to Cyrodiil, she no longer needs the lair she had been using for her operations in Skyrim, and that you would make a good steward for it.
The home, accessed through the bed, is comprised of three parts. The first section, "The Hearth", is a repaired and cleaned up version of the house from the Dreams in Darkness. The main floor features a main bedroom, a child's bedroom with two child-sized beds, a kitchen with a cooking pot. On the table in the kitchen, you can find a Report from Capiton Esdrescus and a Cyrodiil Vampyrum Order Amulet. The bed in the guest bedroom actually leads back to Skyrim. A button on the wall opens the way to the cellar, where you will find an Arcane Enchanter, an Alchemy Lab, a Forge, a Smelter, a Workbench, a Tanning Rack, and a Grindstone.
The cottage's door goes to "The Archive" which is a Nordic Barrow corridor with several bookcases, piles of books like in Apocrypha, and copies of two vampiric artifacts: the Dreamcatcher Coffin and the Gray Host Reliquary. At the end of the corridor, a Dwemer door leads to "The Vault", a Dwemer hall with several mannequins, weapon racks, weapon plaques, and display cases, plus a copy of another vampiric artifact: the Blood of Volrina.
