The content of the game that is included with it but not appears during the actual game play or developer made concepts and content related to the games that were scrapped during development or predate the thief games. It is important to distinguish unused content with hidden content that can still be discovered in certain circumstances during actual game play such as Easter Eggs which go on that page.
As this content does not appear during actual game play it is official not part of the Canon but can still add to the story and atmosphere of the games and, as long is it does not contradict actual game content, can be considered to be something between Canon and Fanon.
An Ogre concept art from Dark Camelot has appeared with unused in-game models for both Dark Camelot and Thief: The Dark Project. Looking Glass Studios has shown this as art for 'The Dark Project', showing the amount of concert art overlap.
Cobrademon - Concept Art for the Cobrademon exists and it appears that the cobra head trophy is based off the head of this creature.
Blur - Concept Art for the 'Blur' shows a naked hairless female who appears as a blurred 'distorted' glass or smoke like effect which making only the outline visible.
Spiderdemon - a Black widow inspired humanoid Spider. Textures for normal 'Spiders' in Thief seem to show leftovers of this idea which was carried over to the Dark Project.
The "spidera" skin file showing a humanoid torso and a three-fingered arm.
A skin file called "spidera" (likely sanding for albino) can be found in the game files that is used by the Yellow Spider which shows human features but differs a lot from the spiderdemon concept art (see picture). This might mean that the spiderdemon that was worked on differed vastly from the one shown in the concept art or that it was an entirely different creature.

The albino spider
Original Bugbeasts (Named Bugdemon) appear Female and pink skinned. These were replaced with the Green unsexed bugbeasts. The Original model based on concept art appeared in the Thief Gold Blooper Reel.
M15accpay[13] - Original accounts for the Downwind Thieves' Guild. Later edited and Cut into 3 pieces. Mistake with the year on the 4th month was not corrected.
m15taffer[14] - A letter from one thief telling another not to steal Lord Randall's Sapphire Vase while giving hints on how to steal it.
Unused48[15] - Dialogue between two thieves about Garrett.
Unused49[16] - Dialogue between two thieves about a thief called Gibson and a Hammerite called Karras.
M10TIP1[23] - A tip giving advice to hide your weapons on Temple grounds. In the final game, no system is in place to make Hammerites react to drawn weapons until Garrett goes attack.
Unused36[24] - Dialogue between Two hammerites about the dust since the renovation work.
From Voice files for various Hammers, It appears Garrett could be given missions while undercover. Hammer1 can ask for a Candlestick from the Dinningroom to be taken to the Chapel. Hammer2 also has the same request but worded in a different way, as does Hammer3. All three will congratulate Garrett when he returns with it and ask him to drop it by the Altar.[25][26][27]
The November 1999 Prototype Intro is much the same as the final version, but features a completely different introduction quote: "We are the Builder's Children. Let the Earth be Cut, Its blood Recast to Serve his will. - The Law of Machine".
Creatures and Items[]
Mechanist Robot - A robotic Soldier appearing only in early preview art.
Early Model previews seem to show the Combat Bot in the gold texture of the Worker Bot and the Worker bot in a light blue texture like, but not the same, as the final Combat Bot.
Concept art Exists of a more Spider like bot design with 2 heads. The boiler is only accessible when the bot is 'awake' and looking around.
Scurry Bot - A tiny bot much like a mix of Worker and Spider Bot exists but does not appear in-game. It is unable to attack.
Venom Blade/Dagger - A possible idea for a magic poison dagger was thought about. Not for use by Garrett but by Necromancers.
Necromancers - Possible AI for the mission 'Waking the Dead' would have featured two different types of Necromancer. Ones which were Mages, and ones with Daggers.
Ghoul - A possible idea of a 'Ghoul' created which is fast, reuses the ApeBeast mocaps, but with new sounds, fast claw attack, and 'eats the dead'
The Balmoraal - A demon with small non-functioning Wings. There would probably be a couple of these in the mission as Garrett cannot kill it, but needs to final a dead one to use one of its horns
Maps[]
'Waking the Dead ' - Idea for a Necromancer mission for T2Gold. Would have featured the Venom Blade, Ghouls, Summing chamber with Demon. This would have featured The Book of Ash as well as ties to the Trickster, and the Mages. An outline for the Briefing has Viktoria send Garrett on a mission to destroy the Book of Ash because of the Mechanists interest in teaming up with the Necromancers. An alternative briefing was to have Garrett found out, after the fact, that he should have stolen the Book of Ash and now has to go after it. This mission was also known as 'Necromancer's Castle (early stages)' and possible placement was directly after 'Casing the joint'.
Raid at Willard Square - Idea for a mission for T2Gold, where the City watch cracking down on crime showing a more 'low down' section of the City. There appeared to be a problem with having a brothel in the mission.
'College-University' - Idea for an undercover mission for T2Gold, with the Aristocracy. There appeared to have been an issue with why Garrett needs to go undercover in this mission. Appears to have been worked on by Mike Chrzanowski or Mike Ryan
Fallen Hammers - Idea for Hammerite mission for T2Gold. possible placement was directly after 'Masks'.
No One Lives Forever - not much is known about this mission for T2Gold. It may have been an possible name for 'Fallen Hammers'.[30]
The Bafford Chronicles - A Special loot item which is referred to in Text but does not appear in-game.

Notes[]
There is a lot of content that goes into making a computer game and there are always bit and pieces which are removed either from the planning stage or as far as the final stages of the game. Thief is no exception to this and looking at this content can be very interesting for the observer.
In an early models video, a four armed creature can be seen after what looks like the earlier version of the Bugbeast and before a Crayman. It is not known if it shares any relation to the the Spiderdemon.[42]
