Quatro Cerberus

Quatro Cerberus (クワトロケルベロス Kuwatoro Keruberosu 四つ首の番犬 lit. "Four-headed Guard Dog") is one of the Legal Guilds of Fiore. Little is known about it, but its members were able to successfully get seventh in the preliminary round of the X791 Grand Magic Games.

Overview
Quatro Cerberus appears to be an eccentric guild distinguished by a peculiar catchphrase: most shown members have the tendency to shout "Your soul will always be wild!" when encouraging fellow guild mates, which is followed by a "Fuoh!" cry. Some of them also sport spiked collars, similar to those commonly worn by dogs, in reference to the guild's theme. Much like Fairy Tail, most members seem to bear the guild's crest somewhere on them, either tattooed on their body or printed on their clothing, and the majority of them appears to consists of massive men with a mildly wild appearance to them.

Location
The guild's location, save for it being in Fiore, is currently unknown. It appears, however, to be located in the same province as Fairy Tail and Blue Pegasus, due to Guild Master Goldmine's presence at the same regular meeting of Fairy Tail's Master Makarov Dreyar and Blue Pegasus' Master Bob.

History
Quatro Cerberus is currently led by Goldmine, who presumably created the guild or took its lead some time after leaving Fairy Tail. The guild has been active for at least some time before year X784, due to its veteran S-Class Mage Bacchus having fought Fairy Tail's S-Class Mage Erza Scarlet several times in the past, and is still active as of year X791.
