Zirconis, also known as The Jade Dragon, was one of the many dragons slain by Acnologia. After his death, his soul was resurrected in the Dragon Graveyard thanks to Wendy Marvell's Milky Way magic.
Over 400 years before the main events of the series, Zirconis stood firmly against the idea of dragons and humans coexisting. He saw humans as nothing more than food, making him one of the more hostile dragons of his era. During the Dragon War, he eventually fell to Acnologia, the Dragon King, becoming just another casualty in the conflict.
