400 years ago, Natsu was born as the younger brother of Zeref, and they lived peacefully in a small village with their parents. However, Natsu died at a young age alongside their parents, courtesy of a Dragon attack. This caused Zeref to research Magic and its relation to life and death and, much later, with Zeref using his dead body, he was revived as the strongest Demon: E.N.D; whose purpose was to kill Zeref. During this time, he also met Igneel, however the Dragon chose not to kill him because he loved him extremely so. With Igneel as his guardian, Natsu became acquainted with Gajeel (with whom he frequently fought), Wendy, Sting and Rogue. All five of them met several times a year, when their Dragon parents got together for meetings. He also had his signature scarf knitted from Igneel
