We were a peaceful people living in harmony with nature in the vast lands of Lyréanor, but this peace was short-lived when our people were defeated by the dark elves, an ancient people even older than this world. It is said that they arrived in Lyréanor by boat and since their arrival, chaos has been unleashed. Proud of their obscure power, derived from dark rituals, they have raised gigantic armies of monsters whose name is synonymous with terror: ‘Obscurus’. 
They went on the rampage, and everywhere they went the grass didn't grow back, life died and disintegrated. Seven, there were seven. The seven dark elves known as the Lords of the Apocalypse. A single gesture from them was enough to strike us all down, a single gesture from one of them was enough to decimate us in blood and terror.
And as I, Foster, contemplate the macabre scene before me, the bloodied and deformed bodies of my fellow elfes beings, and as death grips my soul, a strange sign appeared before me.

Hello everyone! I'm the author of this little book, and I'm sorry to take your attention, but I've got a few things to say to you! I'm in the process of creating a new book that's totally different but stays within the theme, so I'll give you the title and synopsis! If you like the story, could you support it?

Sincerely yours, your favourite author!

Title: Starting out as a slave to dragons.

Synopsis: When Isaac opens his eyes, it's not death that awaits him, but a new life... in a world identical to his own, with one exception: portals leading to monster-infested dungeons are appearing across the globe. If their boss isn't defeated in three days, the creatures escape and wreak havoc.
In this world, awakened hunters are the only line of defence against these horrors. Graded from F to SS according to their magical power, they rule in a society dominated by force. Isaac wakes up in the body of a young boy of rank F, an orphan with no future.
But his destiny changes when he discovers a unique gift: every night, his mind is projected into another world, a nightmare where dragons have enslaved humanity. In this hell, he is just another slave... but he soon realises that this cursed world holds the answers to the future of his own.
To survive and prevent history repeating itself, Isaac must move forward. His only hope? A mysterious system that allows him to absorb the strength of monsters. Armed with a katana, he embarks on a race against time to unlock the secrets of these two worlds and prevent the inevitable.

My world-tree system

The crackling of the flames still echoed in the central hall of Vollua.

Foster leaned against a wall, breathless. He had just stepped out of his inner world.

His whole body vibrated with the resonance of his new power. He could feel the sap of his World Tree pulsing through his veins, an overwhelming and still unstable force, threatening to burst at any moment.

The elves were rebuilding. Wooden houses stood proud under their skilful hands. Roads were being dug through the beaten earth by determined hands. The smell of fresh resin and hewn wood filled the air. Vollua was being reborn, but an uneasy feeling lingered in the shadows of the new foundations.

Foster could feel it, a shiver of alarm running down his spine like an invisible threat, something was wrong.

It was then that a chilling howl shattered the fragile harmony of the reconstruction.
