Urano Metria

Urano Meteoria (ウラノ・メトリア Uranometria) is a Caster Type powerful Celestial spell utilized by Lucy Heartfilia by after transferred from Hibiki Laytis. The spell is initiated once the caster recites the incantation, resulting in several orbs of light gathering around the location of the target(s). The lights would then converge, with tremendous force around the target(s), enough to leave their clothes in tatters. Angel found this out the hard way.

Known Users

 * Lucy Heartfilia - She gained the ability to cast this spell thanks to Hibiki, who transferred the spell into her mind thanks to his Archive magic. However, Hibiki only gave her a one-time casting, so she cannot use Uranometria again unless she learns how to properly cast the spell through practice. After casting the spell, Lucy wasn't able to remember anything of what she has just done, implying that she entered into a trance of sorts in order to activate Uranometreia.
 * Hibiki- it was he who transfered the ability to Lucy via Archive magic, therefore knowing it himself. However, there is no evidence that he is actually capable of casting it.

Trivia

 * The "88 signs" from Lucy's Urano Meteoria incantation refers to the 88 modern constellations. Every Celestial Spirit (gold and silver) used in the series thus far derives its name from that list and it is therefore possible that the spell calls upon the power of all the Celestial Spirits at once. The spell refers to the star atlas Uranometria, produced by Johann Bayer and published in 1603.
 * In the incantation, the Tetrabiblos (an ancient astrology book) and the 88 stellar constellations are mentioned, and also claims that the caster is "the one with dominion over the stars".
 * The spell could be a specific spell for Celestial Spirit mages.
 * Lucy's Uranometria's magic seal resembles Jellal's Heavenly Body's.
 * The Uranometria´s casting spell sequence is very similar to the technique Galaxian Explosion from Saga and Kanon Geminis, both characters from the manga and anime Saint Seiya.
