The mirror had shown him a possible future in which he would suffer a horrible outcome. In this instance an unseen creature, obscured by mists or smoke, lashed onto him with barbed tentacles and began squeezing the life from him. The image was just an image, but the pain was very real.
Stenodus had placed the mirror here on purpose, surmising that his enemies would be vain and conceited, pausing to gaze into the dire device. His own earlier perusal had warned him of the flames that would consume much of his flesh when their sorcerer attacked.
Mirror of Portent
The tall mirror is framed in a polished brass stand and bears the word Prophesy embossed above the glass. Looking into the mirror results in the viewer receiving a full sensory experience of a possible future event. The vision requires the viewer to make a DC14 Wisdom saving throw. Failure results in 2d6 psychic damage and when the possible future comes about, suffering the frightened condition for up to one minute, and making a DC14 Wisdom saving throw to recover from the frightened condition at the beginning of each turn after the first turn. Success on the initial saving throw results in 1d6 psychic damage and no fear condition being imposed during the encounter or event depicted. All depictions are vague and uncertain, though very real to the person gazing into the mirror.
