The Keeper of the Lost City

A long time ago, nestled on the celestial astral plane, there existed a majestic city; full of magic, myth and mystery. This city was known as 'The Lost City', only a few select beings that belonged to the ethereal world knew about its existence. The city keeper was an ancient wizard known as Elethor, gifted with eternal life and unimaginable powers.
Elethor was not always the keeper of the city, he was once an ordinary boy living in a distant village. One fateful day, he stumbled upon an old forgotten tomb. Being curious and adventurous, he dared to venture inside, unaware of the destiny that awaited him.
Inside the tomb, he found an ancient scroll, filled with layered mystic symbols and signs. It was a language that Elethor could not read, but when he accidentally cut his finger, his blood dripped on the scroll, making it glow brightly. The phosphorescent glyphs twisted and turned, forming a set of legible instructions to an unknown place; it was a map to the Lost City.
Intrigued and daring, he followed the map, traversing across perilous landscapes, challenging mountains and bone-chilling deserts. After three years of undeterred determination, Elethor finally arrived at the apparition of a shimmering city, hidden within a large mirage in the desolate desert, the Lost City.
Upon his entree, he was bestowed with extraordinary mystical powers and endless life, with the condition that he would eternally safeguard the city. Accepting the responsibility, Elethor began his life-long tenure as the Keeper of the Lost City.
Maintaining the city was no easy task. Elethor had to ensure the city remained hidden from the mortal realm, safeguarding the precious secrets contained within its ancient walls. The city was also a safe haven for mythical creatures who sought refuge and lived in harmony, under the watchful eyes of Elethor. The Keeper vigilantly protected the city and its inhabitants from any attempts at intrusion or harm.
The peaceful rhythm of the city was interrupted when one day, a dark force known as Zephyr learned about the city's existence. Zephyr was a powerful sorcerer banished from the mortal realm. Consumed by greed, he vowed to seize the Lost City's powers for himself.
The city was under attack; Dark shadows loomed, and scepter-wielding maniacs swarmed the peaceful streets. Yet, Elethor stood tall. With a wave of his wand, he summoned his army of mythical creatures. Griffins hovered in the sky, unicorns charged fiercely, and fire-breathing dragons set the night ablaze.
The war was fierce, Zephyr unleashed his forces of dark magic, and Elethor retaliated with all his might. The battle continued until dawn when Zephyr, cast a powerful spell of destruction towards the city. Elethor knew he had one choice to save his beloved city.
Using his most potent spell, he made the city disappear from the face of the astral plane, with him in it. Zephyr's spell harmlessly passed through the vanished city, and with the loss of his target, he was left powerless, and thus defeated.
In the mortal world, many years passed. Elethor and the Lost City became legends spoke only in hushed tones. Elethor's sacrifice ensured the survival of the city and all its inhabitants, and although it disappeared, its power still lingers, raised to the status of mythology.
Elethor, the keeper, continues to protect and maintain the Lost City in an unknown realm, creating an eternal tale of courage, sacrifice, and duty. The Lost City remains hidden, and Elethor, forever its keeper, is living proof that the true power lies not in immortality or magic, but in the valor of one's heart.
