Aethon: The Last Horizon

Elias Voss never wanted power.
He never wanted destiny.
And he certainly never wanted the responsibility of protecting an entire world.
When a mysterious cosmic force known as Aethon awakens within him, Elias discovers that reality is far larger and far more dangerous than humanity has ever imagined. Strange visions reveal an ancient realm beyond space and time called the Horizon, where forces older than the universe itself wage a silent war.
As cracks begin to appear in reality, Elias learns that Earth is standing on the edge of a catastrophe no one else can see.
Waiting beyond the Horizon is The Null King, a terrifying being whose arrival would mean the end of everything humanity has ever known. Cities, nations, even history itself could be erased as if they never existed.
With each passing day, the power of Aethon grows within Elias, granting him abilities beyond human understanding but every new power comes with a cost. To stand against the darkness approaching Earth, he must become something more than human without losing the person he once was.
As the battle for reality begins, Elias faces an impossible choice.
Remain the man he has always been.
Or become the guardian Earth desperately needs.
