Raven Tail

Raven Tail was a Dark Guild located in Fiore and operating in the Earth Land. In X791, Raven Tail was revoked of its Dark Guild status and was declared a Legal Guild and participated in the X791 Grand Magic Games but the guild was disbanded after the games.

Overview
The entire idea and concept of Raven Tail was based around personal revenge against Fairy Tail after its founder and guild master Ivan Dreyar was excommunicated from the Fairy Tail guild for unknown actions against the guild itself. In X784, Ivan claims his goal is to gain enough money to wage war against Fairy Tail and retained that goal even into the X791 Grand Magic Games where Raven Tail was eger for a confrontation with Fairy Tail.
