Piedra Del Sol: The Sun Stone (太陽の石
, Taiyō no Ishi
Piedora Deru Soru
?) is the Noble Phantasm and trump card of Quetzalcoatl. The megalith of the ancient Aztecs. The Aztec calendar said to show all the world’s past and present. This megalith with a 3.75-meter diameter appears overhead, this being a “gate”, and it drags out a portion of her Authority because of Quetzalcoatl being the great foundation of this very activity. Intense solar winds rampage over a vast range, and it will certainly be reflected as god’s majesty itself.[1]

When used in the Babylonia Singularity, while retaining half of her Divinity, Quetzalcoatl's usage of this Noble Phantasm still managed to evaporate a majority of Tiamat's Chaos Tide. Ishtar speculates that had Quetzalcoatl used this on the city of Uruk, the entire city would have been vaporized.[2]
