Inspiration for The Zashin Legacy

I used to say I wanted to be an author before I could tie my own shoelaces. 

After spending five weeks in Thailand learning Muay Thai, followed by three weeks in Japan soaking up the culture, I found the inspiration to finally write my own story. 

That's not all--I love consuming fiction, whether it's movies, books or anime. I am beyond inspired by the genius in some of these pieces.

If you loved any of the below - I think you'll really enjoy The Zashin Legacy. 

Watching or reading is one thing: living it is another.

 

Having started boxing seven years ago, fighting has been a big part of my life and has played a big part in shaping my character. 

In summer 2025, I travelled to Thailand for five weeks. I stayed at a Muay Thai camp for nine days before travelling the country, training at as many different gyms as I could. It was indescribably immense, and I instantly fell in love with the sport..

I then traversed Japan alone, finding inspiration in every spot of nature or architectural beauty.​

The fights that go down in this story are are calculated descriptions of real techniques.​ ​The setting is largely inspired by my time in Japan.​ And finally, each and every character has a piece of me in. ​
