Syl was given a choice by Gramps when they died. Reincarnate as a regular person or embark on a daring experiment. Driven by a desire to honor Gramps and a sense of adventure, Syl chose the latter... only to awaken as a lowly slime. A farmed slime. The life of a farmed slime was cruel.

This was not the life Syl had envisioned. So, they made a daring escape to the wilderness!

The usual result of a human taking a runaway semitruck head-on is a very sudden, very fast track to the pearly gates. But for one newly noncorporeal man, there's another option: become a dungeon.

Admittedly, a small run-down, somewhat unimpressive dungeon (more of a house, actually), but you gotta start somewhere, right?

I used to be the greatest Earth Mage in my world. The head of the entire Order of Architects.

But I failed to account for one thing: during the course of my long life, I'd accumulated too many enemies, and they had decided to spoil my retirement. So they died along with me.
