Fable Anniversary Demon Doors can be found in most of the main regions in Albion, and while they are easy to find, they can be really hard to open.
The Demon Doors are guarded by some sort of large faces which demand something before opening. Most of the requests cant be satisfied when you find the Demon Doors for the first time, but it is a good idea to speak to it to see what it demands.
When you open a Demon Door you can access a new area where you can find a chest containing clothing items, armors, Legendary Weapons, and many other items.
There are 15 Demon Doors in Fable Anniversary and if you manage to open 12 of them (three are part of the story) you get the Open Saysmemiddlefinger achievement (or you can choose the easy way and just show your finger to one of the Demon Doors).
The Fable Anniversary guide below explains how you can open each door through a series of hints and tips.
Fable Anniversary Demon Doors Locations
Demon Door #1 (Heroes’ Guild)
You can find the first Demon Door in Heroes’ Guild area. It is in the south side of the map, past the bridge and next to the waterfalls. You need a light to open the Demon Door.
You will get a Lamp after you pass the final exam of the Guild Training. When you have you can return to the door and it will open if its turned on. In the newly opened area there is a chest that has an Elixir of Life. Before getting outside dont forget to loot some books and a tattoo.
Demon Door #2 (Rose Cottage)
The Demon Door in Rose Cottage is easy to spot when you access the area. It is also very easy to open. Just give something as a gift to the door, something cheap such as chocolates or roses.
Inside the chest thats in the area guarded by the Demon Door you can find a full Will Users Bright outfit.
Demon Door #3 (Darkwood Marshes)
Another Demon Door that can be opened without too much effort is the one in Darkwood Marshes (the effort depends on your character equipment and upgrades).
Its on your left hand side when you access the area from Darkwood Entrance, you cant miss it. In order to open it you have to defeat its guardians, consisting of several waves of Hobbes.
Once defeated, the Demon Door will open. Follow the path inside to find the chest. Loot it to get a full Will Users Dark suit.
Demon Door #4 (Darkwood Bordello)
The Demon Door in Darkwood Bordello can be found around the house. Its request is for you to sleep with 10 women in the Bordello. As the task says, find yourself a woman that has a price suited to your pocket and sleep with it ten times.
Due to the nature of the task, you must open the door before completing the mini quest thats available in this area if you follow the good path.
If you follow the evil path you can complete the quest and then sleep with the women for free. Inside the chest guarded by the door you can find a Pimp Hat.
Demon Door #5 (Greatwood Gorge)
Theres a Demon Door in Greatwood Gorge right next to Greatwood Cullis Gate entrance and most definitely you will encounter it early during your playthrough.
However, only characters that have the evil alignment bar maxed out can open it. Otherwise you need to commit a crime in front of the door, something thats worth 50 evil points.
If you follow the good path you can open it in an alternate way, but only later in the game, after you unlock some distinct areas. In Darkwood Camp and Twinblades Camp you can purchase Crunchy Chicks, which give evil points while eaten. Buy 10-11 and eat them in front of the Demon Door to open it.
Inside you can find a legendary weapon named Wellows Pickhammer (cut through some thorny wines to reach the chest).
Demon Door #6 (Greatwood Caves)
The Demon Door in Greatwood Caves is one of the hardest in the entire game, at least early on when you find it for the first time. The door tells you to show it a higher combat multiplier, so you need to return and speak to it again when your multiplier is at least 14.
To get a high combat multiplier enter the Hobbe Caves and defeat all the enemies (or most of them) as fast as you can. Then quickly go outside and defeat the spawned Hobbes (your multiplier drops a lot when going from one area to another). As soon as you reach 14 talk to the door to open it.
The chest thats inside holds the Cutlass Bluetane Legendary Weapon, which is very useful for a decent part of the game.
Demon Door #7 (Witchwood Stones)
The Witchwood Stones Demon Door is the first one that it is part of the main story, so it cant be missed (Find the Archaeologist). To get the Demon Door to open you must spell its name by hitting four stones which are located in the northern side of the map.
Check the letters of the stones with the action button and then hit them to form the word HITS. There are many things to search for in the cavern guarded by the Demon Door (a 15 Key Silver Chest, a Resurrection Phial, Chainmail Leggings, a Sapphire, a Ruby, a Howl Tattoo).
Demon Door #8 (Knothole Glade)
There is a narrow path in Knothole Glade (outside the town) that leads to a Demon Door. The door opens only for those who hit it hard enough with an arrow.
If you have a decent bow and your skills are high enough you should open it without much trouble. Otherwise you can return later when your character has better stats. Inside the chest protected by the Demon Door you can find an Elixir of Life.
Demon Door #9 (Abandoned Road)
You can open the Demon Door in the Abandoned Road area only you if own three specific costumes. The door demands you to bring his old friends to see them, hence you can trick it by dressing like them.
The first costume is the Bright Plate Mail, which is probably the most difficult to find. Some parts can be bought from Knothole Glade, but the trader at the Arena holds the whole set (at a higher price), so dont forget to buy it before fighting in the arena during the main quest.
The second suit is the Dark Will Users Outfit, which can be purchased from the merchants in Knothole Glade or Hook Coast. However, you already have one if you opened Demon Door #3.
The third costume is the Bandit Outfit which can be found in the chests in the Abandoned Road during a main quest. The Demon Door guards The Dollmasters Mace, a Legendary Weapon.
Demon Door #10 (Barrow Fields)
The Demon Door in Barrow Fields can be opened at any time assuming you have enough food. The door opens only if you are fat enough.
Therefore, eat enough Apple Pies or Red Meat when you have a full health bar to gain weight (it takes around 25 Apple Pies or 27-30 pieces of Red Meat).
You will unlock the Definitely Not on Rails achievement when you are obese enough (if you havent already unlocked the achievement by exploring every region in Albion). When the Demon Door opens collect the Will Masters Elixir thats hidden in the chest.
Demon Door #11 (Headsman’s Hill)
You can open the Demon Door in Headsmans Hill if you defeat a Hero in its presence. You can defeat Thunder when Lady Gray asks you to marry her during the Mayors Invitation quest.
If you choose to expose Lady Gray the door will stay shut. As a reward you can find a Silver Chest in the cave.
Demon Door #12 (Grey House)
The Grey House Demon Door will open only if you marry someone with a title. The only person in the game who fits the description is Lady Grey in Bowerstone North, so the only way to open the door is to marry her instead of exposing her. Behind the door you can find the Legendary Weapon named Ronok the Axe.
Demon Door #13 (Lychfield Graveyard)
The Demon Door that can be found in Lychfield Graveyard is story related. It opens only for Nostro, hence you have to find his gear during the main quest The Graveyard Path.
The door leads to the Old Graveyard Path.
Demon Door #14 (Lookout Point)
You can find a Demon Door in Lookout Point near the end of the game that opens automatically as part of The Prophets of the Fire Heart quest.
Demon Door #15 (Necropolis)
The final Demon Door is in Necropolis. You must give all 30 Silver Keys to the Demon Door if you want to get inside.
Be warned that you will lose all your Silver Keys, so make sure to open all the Silver Chests before handing over the keys. Inside the chest guarded by the door you can find The Bereaver Legendary Weapon.
