It lies beneath the ground, under a massive mountain range. History books attest that hundreds of years ago all mankind was trapped inside. Nowadays people venture within its walls in search of treasures, fame and knowledge. Bigger than any kingdom, it provides food and resources to entire countries. Bustling human cities and menacing monster lairs can be found in its enormous caverns. It is The Dungeon, and in the world of Seelebierg everything revolves around it.

"Hi, I'm… Well, I don't remember my name, one day I woke up in this hellhole without my memories, even worse, I was a random filler mob whose only purpose is to annoy adventurers and feed stronger monsters. Since then my life has been a disaster, but I will get my memories back and escape from this place, it doesn't matter how many tries it takes.Oh, there is also that guy, Simon, he grew up in some mountain in the middle of nowhere, I swear the only thing in his mind is hunting monsters."

"My name is Simon, I was a humble hunter who grew up in the mountains, one day my parents sent me with my uncle to become an adventurer, the dream job of any young boy. I was doing great until our party crossed paths with this strange monster in the depths of The Dungeon, I swear I won't rest until I have hunted it down."
