- "An infamous heirloom that once caused a terrible tragedy."
- —Description, Dissidia Final Fantasy.
At the start of the game, Cecil Harvey has completed his mission to bring the Water Crystal from Mysidia to Baron. However, when Cecil begins to question the motives of the King, he is dismissed from his post with the Red Wings and is ordered to deliver a carnelian signet to the village of Mist. Kain Highwind is also ordered to accompany Cecil.
The journey to nearby Mist is simple, with Cecil and Kain only passing through the Mist Cave and slaying the Mist Dragon at the cave's end. However, once they arrive at Mist, the signet suddenly activates and Bombs are released to set the village on fire. Cecil and Kain realize that the king had lured them into a trap, resulting in the purging of the resident summoners.
Carnelian Signet appears as a trade accessory, which grants +4 Luck and can only be gotten through battlegen using the Red Wing Ace Friend Card. It is used to create the "Easy Come Easy Go" accessory.
- "An antique ring that caused a tragedy and sought by all who gaze upon it."
Carnelian Signet is a trade accessory that grants +4 Luck when equipped, and can only be found in two parts of the Confessions of the Creator.
A signet is a ring, typically made of carnelian, used to seal letters with wax by means of pressing a certain symbol (usually a coat of arms) onto the envelope. The seals created by signets were also used on official documents in lieu of a written signature.
- "Carnelian Signet" was an updated term for the translation of the Nintendo DS release. Tom Slattery commented that the original term "Bomb Ring" would give away the plot twist of the item's true purpose.
