Mysteries of Sacra - High Fantasy / Progression Isekai

Hello everyone, I've been writing for two months now and wanted to share my story and see what you guys think. It's inspired by a lot of Eastern stories but also by Western magic systems and fighting. The focus is on the MC growing emotionally and struggling with his growing power.

Here is the link https://www.royalroad.com/fiction/133253/mysteries-of-sacra, and you can find the blurb below :)

Thrown into a world of beasts and magic, Kai must fight to survive and find a way back.

***

Kai was just a teenager. Now he’s bonded to a beast, hunted by monsters, and wielding powers that shouldn’t exist.

One moment, he was on Earth. The next, he’s ripped into Sacra, a savage realm ruled by spirit beasts, ancient mana, and deadly trials. Alone, untrained, and hunted, Kai has one goal: survive.

But survival won’t be enough.

After saving and bonding with Umbra, a mysterious beast cloaked in shadow, Kai begins to rise. Together, they face brutal battles, monstrous generals, and ancient forces that should have stayed buried. As Kai evolves into something more than human, whispers stir of a lost war and a soul that could reignite it.

Power is everything. And Kai is about to learn what it costs.

***

What to expect:

Follow Kai as he struggles to balance unimaginable power with the fragile threads of his humanity.
In a world where kindness is weakness and morality is a luxury only the strong can afford, Kai must decide who he wants to be and what he's willing to sacrifice.

His companions are more than allies; they're his anchor.
Umbra, fierce and loyal, and Scry, wise and offlandish, refuse to let him lose himself to the darkness growing within.

To escape Sacra and return to Earth, if that’s even possible, Kai will have to become something more than he is. 

Along the way, he’ll find allies, rivals, and maybe even a flicker of love…
But every step forward brings him closer to a prophecy no one dares to speak.
