I think that may be involve Celestial Spirit Magic. Urano Metoria is called as Ultimate Magic of the Stars and in the incantation mention "O 88 Stars of the heaven... Shine!" possibel the 88 constellations used in modern astronomy, which are inspiration to Celestial Spirits. Plus all users have connection to Celestial Spirits Magic. Lucy is Celestial Spirit Wizard, Gemini who support Lucy to use Urano Metoria is Celestial Spirit and Hibiki was boyfriend of Karen Lilica who was also Celestial Spirit Wizard probably pass the spell as gift, and keep as last memento of Karen. It possibel that by summoning powerful beings from another dimmension and use the power of stars made Celestial Wizards being hunted and killed due to their power.
