Driftshade Cellar is a dungeon in The Elder Scrolls V: Skyrim
Inside Driftshade Refuge in The Pale
Go around the first stack of barrels to the left. Look behind them to find a chest. After that, turn to the North and then follow the passage as it bends around to the East. Be careful as it turns back to the North. There is a pressure plate sitting in the middle of the floor. On the far side of the spiked wall that is triggered is a member of the Sliver Hand waiting to come after you. To the South is a locked cell (Adept level) with a dead werewolf inside it. Continue along the corridor until it turn to the right. Follow the path downward. Follow it to the wooden door. Open it up.
This room has 2 more Silver Hands to deal with. Again, one ranged and one melee. Defeat them. Go to the Eastern side of the room and look on the bookcase there. You will find the Light Armor skill book: The Rear Guard. Read it and then turn to the snowy passage to the North. Head on through that.
This leads to another room with a pair of Silver Hands. Defeat them and head up to the 2 cages on the upper level. One has a dead horse and the other holds a leveled Werewolf. Both are locked (Apprentice level) so what is inside is contained.
Turn to the North and head on through to the torture room. You will find another member of the Silver Hand waiting inside for you. Take them out. Loot the dead werewolf and then head through the next door.
This leads to a large room with 2 more of the Silver Hand below you. One is sitting by the fire while the other patrols around the area. Pick them off. Go behind the fireplace to the Northwest. You will find a bookshelf with some useful potions and an apothecary's satchel that you can get some Alchemy Ingredients from. After that, turn to the South and head through to the next part of the cellar. This will lead you to a door that reconnects to the Driftshade Refuge.
