*# 《Legend of the World Tree》 Intro
In the beginning, there was nothing.
Neither light, nor darkness, nor life, nor time existed.
Then one day, at the center of the world, a massive World Tree sprouted.
Its roots stretched down to the endless Underworld, embracing all souls; its trunk supported countless continents and civilizations; and its branches reached for the heavens, the stars, and the realm of the gods.
Beneath the World Tree, great kingdoms with thousands of years of history were established, and the seas of the infinite horizon hid mysterious islands and lost ruins.
Meanwhile, in the deep abyss of the earth, an eternal darkness breathes, and within the massive Demon King's Castle, an unfathomable army waits for the day of war.
And at the heart of the continent lies the Great Magic Tower City, the heart of magic.
Five great magic towers exist here.
🔥 Tower of Fire. 🌊 Tower of Water. 🪨 Tower of Earth. 🌪 Tower of Wind. ⚡ Tower of Lightning.
Each tower guards the elemental power that sustains the world, and countless mages and sages have inherited that power.
However...
The long-maintained balance has begun to crumble.
The light of the World Tree grows dim, the gates of the Underworld are slowly opening, and the Demon King's Army seeks to swallow the continent once more.
Now, the fate of the world rests on the choice of a single person.
Will you be a hero?
Will you be a mage?
Will you be a king?
Or...
Will you be the one to bring about the end of the world?
Now, the legend begins. *
