Frieren/History

Frieren is the sole survivor of an elf village which was destroyed by the demons. She was then rescued by Flamme who took her on as her apprentice.

After at least 900 years of life, she joined the Hero Party as its Mage, and journeyed to the Demon King's Castle in Ende in order to defeat the Demon King. Ten years later, after defeating the Demon King, the Hero Party watched the Era Meteors together and disbanded with the promise of seeing the Era Meteors again in 50 years.

Afterwards, Frieren planned to explore the central provinces for a century, and continued to journey around whilst acquiring magic. After 50 years passed, Frieren reunited with Himmel, Eisen, and Heiter in order to see the Era Meteors together. Sometime after, when Himmel passed away, she attended his funeral.

Twenty years after the Hero Himmel's passing, she sought out Heiter in the outskirts of the Holy City Strahl and stumbled across a young Fern, whom Heiter had saved. When Heiter asked Frieren to make Fern her apprentice, she refused, citing the high death rate of mage apprentices on the battlefield; however, Heiter then requested that she decipher a grimoire on resurrection and immortality and train Fern in her free time. After five or six years, she had inadvertently ended up training Fern to a point where she was no less capable than an adult, and finally agreed to take on Fern as her apprentice. After Heiter passed, she and Fern visited his grave before setting off on a journey together.
