But beyond its tranquil borders, something has awakened. Whispers of vanished heroes, creatures long thought extinct, and shadows that no longer sleep begin to creep back into the land.Liora never wanted to be a hero. Orphaned young and shaped by loss, all she’s ever known is survival base on love and kindness. But when a brutal invasion exposes the kingdom’s deepest vulnerability, she’s thrust into the heart of a battle far greater than herself. Her light-element magic—once dismissed as minor and passive—may be the key to a new era of power.As Sanctora struggles to adapt, Liora must decide whether to follow the path laid out by those before her… or blaze a new one through fire, blood, and truth.Epic, emotional, and filled with slow-burning revelations, Ancient Beast Summoner is a story of legacy, buried power, and the girl who just might change everything.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

This Meteor Tear, unbeknownst to the young man, merged into his body, and like a caterpillar transforming into a butterfly, the young man metamorphosed... And with that transformation, everything changed. And his father finally came to realize the astonishing strength of the son he had never truly invested his Heart Power in...
