In the magical world of Lethren, our protagonist, Aska, finds himself waking up in a strange forest. He’d found himself on the outskirts of Velen Lon, the greatest labyrinth city on the continent. Realising he’d arrived in a highly advanced magical civilisation. He and his friends decided to explore the labyrinth. After all… it was more profitable than a regular job but also… way safer than the outside world. If you can't stand really weird stuff, it's probably not for you.
