Item from Fire Emblem by Intelligent Systems / Nintendo
The hearts of murdered dragons set into weapons of war — the power source for every Heroes' Relic and the most damning evidence of Fódlan's original sin.
Crest Stones are the power sources embedded in Heroes' Relics. Each one is the heart of a Nabatean — extracted during Nemesis's massacre at Zanado and installed in weapons crafted from the same victims' bones. They are the Crest system's original sin made tangible: every noble family's power derives from a specific murdered dragon's remains. A Crest Stone can also transform anyone without the matching Crest into a Demonic Beast — a corrupted monster driven mad by the incompatible Nabatean energy. This is the Relics' safety mechanism and their greatest danger.
Glowing crystalline orbs — red, blue, or green depending on the Nabatean they were taken from. They pulse with contained energy and feel warm to the touch. Each one is unique, because each one is the literal heart of a specific murdered dragon.
