The Secret Garden of Eternity

In a quaint little village in Switzerland, named 'Einzbern', nestled among the majestic Alps, there existed an ancient legend about a secret garden. The legend had it that this garden held the power of eternity and whoever found it, could live forever.
Despite its scary implications, the adventurous spirit that lies in every man had many venture towards it, only to return empty-handed, a little older, a little wiser. The tale of this secret garden was passed down generation to generation until it reached a bright young lad named Liam.
Liam was a curious and fearless child, enamored by the tales of mystery and adventure his grandmother told him. He was particularly fascinated by the story of The Secret Garden of Eternity. As time went on, this fascination grew into a deep-seated resolve to find this elusive garden of eternity - he wished to unravel its mysteries and prove its existence.
His journey commenced as he bid adieu to his worried grandmother and set off, armed with a small knapsack filled with food, water, his grandmother's old map and a whole lot of curiosities. He passed through deep valleys, ominous woods, and treacherous creeks. His travels were fraught with danger and difficulties, but the allure of the garden kept him going.
Unbeknownst to Liam, a raven, seeing Liam crossing the territories without fear, had started following him. The bird, named 'Thena', was the keeper of the garden, bestowed upon her by the deities that created the garden. She silently observed Liam, curious about his bravery and tenacity.
One chilly evening, when Liam was about to lose hope, he spotted a raven that seemed to beckon him. On an instinctive whim, he decided to follow it. Thena led him through a hidden path, laden with flowers of all kinds, blooming with life, a stark contrast to the icy landscape they were in. At the end of that path was an enormous, ethereal looking gate. His heart leaped with joy as he realized that he found it - the Secret Garden of Eternity.
Overwhelmed, he stepped inside to see the grandeur unfold in front of his eyes - an endless expanse of colors, textures, and fragrances. The plants and trees shimmered as if blessed with life. In the middle was a beautiful crystal-clear spring filled with an elixir emitting an almost divine aura, confirming the legend.
Thena, now human, emerged from behind a blooming glory bush and spoke up, 'This water gives you life, endless life. But it binds you here with me, forever'. A wave of realization hit Liam about the gravity of his decision.
Liam, moved by the beauty of the garden, and the burden of eternity, resolved to protect the garden. He chose to drink the elixir, to live an eternal life as the Gardner just as Thena did as a caretaker.
Their days turned into years, their years into decades, their decades into centuries, and the garden lived on, cloaked under the guise of a legend. Liam did something that no man could ever do, he found the Garden of Eternity only to hide it back again into its secrecy.
The villagers now tell tales of a young boy wanderer who ventured off into the Alps and was never seen again while somewhere high up in the wintery mountains, in the heart of the Secret Garden, the duo kept each other company in silence, their stories, unheard as they cultivated the garden, protecting it, nurturing it, living on for all eternity.
