The Mask of Deceit is a full face mask carved from Ebonwood, in the shape of a crude and aristocratic Keldian. There is no space for a mouth, and the eyes are solid wood, but a faint tracery of ivory outlines the features. A thong made from woven Keldian hair is threaded through two holes in the edge of the mask.
As soon as the Mask is donned it cleaves to the face of the wearer, burning into their face for 1 Lethal Damage. Once attached the Mask takes on the shape of another person. If the wearer succeeds in an Int roll when donning the Mask (and chooses to do so) the Mask will adopt the face of someone specific that they visualise. Otherwise the Mask will take on the appearance of a random Keldian, of any age, sex, or breed. This illusion extends to the rest of the wearer's body. To all intents and purposes they are transformed into another person, so exact a copy that even a close friend could not tell them apart by sight or voice (though the Mask does nothing to impart knowledge, mannerisms, or patterns of speech). If attempting to imitate someone while speaking or interacting the Mask confers +8 Disguise.
The Mask maintains its disguise until removed, and cannot change its shape without being removed and donned again. Each day, when the first star passes the ziggurat of Ur, the Mask inflicts another Lethal Damage if it is still being worn. Each time the Mask is removed the wearer must make a simple Spirit roll. If they fail they forget some basic fact about their own history or identity. By the time they have failed seven times they no longer have any idea who they are, and will adopt the identity of the last person they imitated using the Mask.
