Fable II

There are 9 Demon Doors to be found in Albion, arranged alphabetically. If you have already opened all 9 doors before downloading "See the Future", you will get the achievement when you load the game with the DLC for the first time.

Bloodstone
Near the entrance to Bloodstone from Wraithmarsh, amongst the sepulchers. Play the Lute for the door until it asks you to stop, then stop on green.

Bower Lake
Take the left fork on the road to Bowerstone. You need the following expressions to perform in it's play: Bloodlust Roar, Blow Kiss, Dance, Fart, Growl, Laugh, Middle Finger, Point and Laugh, Vulgar Thrust and Worship.

Bowerstone Cemetary
Follow the main path, on the right.
This door wants meat, so kick some chickens into it.

Brightwood
Near a wetland area in the south of Brightwood.
First it will ask you for some cheese. After coming back with cheese, it will then make more demands: You must wear either dreadlocks/mullet, muttonchops/handlebar moustache, Bandit Bandana/Yokel Hat, Tart Skirt/Noble Trousers, and a Noble Gent's Shirt/Corset.

Fairfax Gardens
Take either of the side paths under the castle stairs.
Open all the other doors first.

Oakfield
Near the beach.
Bring someone to the door and use the Propose Marriage expression.

Rookridge
On the main path.
Your Dog must perform 5 different tricks.

Westcliff
You must have at least 50% corruption to open this door. Try raising the rent or eating yummy food.

Wraithmarsh
Near the warp point for the area, you must bring it an audience to watch it's play. Bring as many as you can, I got a bunch from Bloodstone and it worked fine.

There are 9 demon doors in Albion with each one offering treasure if you can fulfill its request.

-Along the Bowerstone Road in ROOKRIDGE, you come past a small bandit camp with a large boulder in the centre of it. As you follow the path you'll see a demon door on your right. This requires getting your dog to perform tricks. - rewards you a Potion of Life

-In Oakfield, if you look at your map where the path forms a loop, at the top of this path near to the waters edge is a demon door. The door requires a marriage proposal be performed in front of it. If you are already engaged/ married you must blow a kiss to your beloved in front of the door. This gets you Hammerthyst (legendary mace).

-Bowerstone lake, the very SW path leads to a door that wants you to perform expressions - Bloodlust roar, fart, middle finger, worship, blow kiss, growl, point & laugh, dance, laugh, thrust you'll get a Lucky Charm Augment.

-In Bowerstone Cemetery, when entering the cemetery from Bowerstone, on the right side he requires meat to open - kick a chicken at the door. You'll get the following potions - Balverine strength potion, Practiced skill potion, and Infused Will potion.

-Brightwood, just north of the Westcliff entrance, but south of the lake with three small islands in it (south west on the map). Requires cheese. Mutton chops (Bowerstone Stylist), dreadlocks (Bloodstone Stylist) and then he will want you to wear a Strumpet Skirt (Tart Skirt) - Bloodstone, Farmer's Hat (Yokel Hat) - Oakfield, Posh Shirt (Noble Gent's Shirt) - Bowerstone Market. If you are already wearing any of those items he will ask for different ones. You'll get a Merchant's cap, Knotted Shirt, and Harlequin Trousers for your efforts.

-WraithMarsh - North of the drowned farm on the right path requires an audience. Grab 10 followers

-Westcliff- southwest corner of map. Right of the path when heading away form howling halls. Be halfway corrupt or more and will get you a Calavera (legendary mace).

If you have already opened all 9 doors before downloading "See the Future", you will get the achievement when you load the game with the DLC for the first time

None of the solutions here provides a very clear description of where the doors can be found so I searched a lot and found this great guide with pictures of the maps with a red dot marking each door location (also great site for other achievements like the silver key one):
