Changestone (CTD)
The Changestone is a legendary Faerie Treasure and one of the two Unseelie stones among the four Immortal Eyes.
Overview
The Changestone, a fiery ruby, was given to the satyrs to guard. It confers the power to change its holder's appearance in the mortal world and tends to alter circumstances in their favor, at times to the detriment of those around them. Its real magic, though, lies in its ability to transform someone into their true self; restoring such a one to their faerie nature. Some believe the gem can even reverse the process of mortal aging.
System
The holder of the Changestone has access to Primal 5 (Elder-Form), and the Soothsay cantrips Fair is Foul and Foul is Fair, Augury, and Fate Fire. The user may invoke these powers without needing to perform bunks, but a point of Glamour must be spent when the Changestone is used against non-fae. If the holder of the gem has their faerie nature stripped away by chimeric damage or proximity to cold iron, the stone will replace their lost Glamour at the rate of one per hour until they recall their true nature.
