It was a clear day. Not a cloud in the sky. Which is why that bolt of lightning caught everyone by surprise. Especially me who survived just long enough to realize what had happened.

The next thing I know I'm standing next to this vaguely female figure who somehow seems to be literally wearing light like an overcoat. She explained that my death was an accident and since they had technically caused it, albeit accidentally, they were going to let me pick my next life. She did warn me though that once the decision was made it could not be unmade. After confirming that I understood she walked me through the options.

Option 1 is to be reborn as a demon lord. As a demon lord I would control a vast territory and command a mighty army.

Option 2 is to be reborn as a human. I could go back to my old world or choose from billions of other worlds. Some of the worlds even contained actual magic. Looking through the list I discovered that earth was not the only world without magic. Though worlds without magic were exceedingly rare.

Option 3 is to be reborn as a beastkin. There were all kinds of different types of beastkin I could be.

Option 4 is to be reborn as a dragon. Surprisingly there were a large number of different types of dragons I can be. Some even existing in worlds without magic somehow.

Option 5 is to be reborn as a dungeon. Not much information was given about this option. When asked she said it was because dungeons technically exist in their own pocket dimension. Also, dungeons don't really have defined types. Apparently, being able to change everything about themselves makes them, by definition, undefinable.

"Why is being reborn human option two?" That was my first question. She explained that the options were listed in order of popularity. Ok, I think we'll just skip right past the fact that this apparently happens often enough that the options have a popularity ranking.

I can see demon lord being a popular choice. Not one I'd ever make myself as it does by its very nature seem to come with some very serious strings attached. Option two is just boring. I've already lived as a human once. I can understand some people wanting to stick with the familiar but I'm ready for something new. Becoming a beastkin tempted me for a bit. The closer I looked though the less I saw that distinguished them from humans. Becoming a dragon was very tempting. Dragons were extremely powerful being after all. Unfortunately, they were also extremely large targets for people wanting to make a name for themselves. That just left one option.

After talking with the strange being for a while I decided it was the right choice. Being a dungeon would have some serious drawbacks. Being stuck in one place. Not being able to interact with people. Being a literal inanimate object. It had one major benefit though. As a dungeon I would technically have an unlimited life span. The only way for a dungeon to die is for the core to be destroyed. There was also the fact that I could be as creative as I wanted. Literally becoming my own canvas. Honestly though it was the lifespan that did it. Who wouldn't want to live forever?

After making my selection I felt myself being enveloped in a warm blanket of light. The next thing I knew I was in the middle of a five-by-five-by-five-meter room. How I knew the exact dimensions of the room wasn't immediately clear but somehow, I instinctively did. The next thing I knew there was a wall of floating text in my face.

I've read enough stories to know what mana is. I'm guessing world energy is some kind of currency unique to dungeons. Why would a dungeon need currency though? As if to answer my question another wall of text appeared. This one containing a list of things that could be purchased with World energy. Some even appeared to have subcategories. In fact, all but one had subcategories.

I can't really call myself a dungeon without rooms, so I go ahead and spend 50 World Energy on 5 rooms. As for the rest, well If I'm going to be a dungeon I'm going to need creatures for delvers to fight. Selecting the creatures tab I'm presented with a list that just keeps growing. In exasperation I ask nobody in particular if the list can be sorted to only show the ones I can afford. As If in response to me the list suddenly changes. Now all the creatures being shown are ones I can afford. The list is still way too long though. I need to narrow it down further. "This could take a while." I sigh to myself as I roll up my metaphorical sleeves and prepare to dive in.
