Sabrina Mercury

Sabrina Mercury (サブリナ・マーキュリー Saburina Mākyurī), who affectionately loves to be addressed as Brina as she finds the nickname adorable, is a member of the famous Independent Guild, Dawn Horizon and is also a Dragon under the guise of a human. With her true identity being Athelza, the Cosmic Dragon of Enchantment, Sabrina was a participant of that took place several centuries ago and was an adamant believer that humans and dragons can and should coexist with one another. After the war had progressed to uncertain heights, Sabrina endured severe injuries and finally withdrew herself from the battle and went into hiding to recover her strength.

Since leaving the war and travelling across Earth Land, Sabrina has joined a multitude of different organizations to pass the time and also gather information about the many different forms of Lost Magic that interested her. During such time, she came into contact with the legendary, and through an agreement, studied under him while also acting as one of the  for the. As one of the twelve strongest mages of Alvarez, Sabrina became an idol to the people of Alakitasia for both her unmatched magic, which earned her the nickname Divine Mistress of Magic, along with her matchless beauty and incredible buxom, which hilariously gave her the title Busty Conqueror, a name she thinks of in good humor. .

Sabrina's time on was incredibly beneficial for the studious dragon as she learned a great deal regarding the history of magic through numerous books that Zeref had either written or found. After several decades however, Sabrina's thirst for more knowledge and exploration outside Alakitasia became unbearable for the dragon and she parted ways with Zeref after thanking him for all of the resources he had provided her. Once she had departed her former residence, Sabrina set her sights on the Eastern continent known as and quickly made herself known to all of the guilds and mages for her mastery over many forms of magic. An endless amount of people requested Sabrina to join their guilds, with all of them failing to make any sort of worthwhile impression on the alluring mistress who quickly dispatched every last one of them.

Almost feeling that her decision to come to Ishgar was a mistake, sabrina was pleasently surprised when she met her future guild master Ludius Grande Di Tetsuya, who appeared from out of nowhere and challenged Sabrina to a duel to verify her strength. Having no reason to object and amused by Tetsuya's confidence, Sabrina battled against the confident mage and the two dueled one another for several days, with their bout finally reaching its climax on the third day when Sabrina finally revealed her true form as a Dragon. To Sabrina's complete surprise however, Tetsuya wasn't fazed at all by her appearance and charged at her with everything he had but ultimately fell with one swipe of Sabrina's mighty tail. Her interest in Tetsuya growing, Sabrina tended to his wounds and brought him back to her place of residence where she was offered a place in Tetsuya's guild as he was fascinated with Sabrina. Thinking the matter over, Sabrina's curiosity and desire to see what kind of path Tetsuya would follow and how strong he could potentially become, along with her quite obvious attraction for the younger mage who she fully planned to have her way with, made her happily accept the invitation.
