Hyera Prelude to the darkness

Synopsis
Arcadio led an almost normal life... until it stopped being one.
Everything changed the day he was dragged into a world where the impossible stopped being absurd and became real danger.
Turned into a witness to something no one should see, he's forced into a desperate search to reclaim what was taken from him. But the price is high: his own life... and that of his best friend, Damian.
Neither of them was ready for what was coming.
Because along the way, they won't just face the unknown, they'll have to ally themselves with an uncomfortable presence, unstable... and absolutely necessary.
And when dangerous creatures begin closing in around them, they'll understand something brutal:
Reclaiming what was lost won't be the hardest part.
Surviving... will.
