Perhaps the greatest thing about the universe is that it's not alone--as I have personally discovered via accidental dimensional travel.
Unfortunately, the fact that the indigenous populace considered me a threat and are all out to reave my body of its head; all for the sake of claiming whatever bounty they marked on me.
Perhaps I should begin from where this unfathomable mess originated from, aye?
Back in the halcyon days of where I followed a set routine, it was relatively boring... and peaceful. What I miss the most is the peace.
Wake up, don't bother going outside the house, waste away Summer like it was just another day, and of course sit in front of the computer for hours on end--that was my routine.
One day, I found a book. It was dubbed by some entity that is beyond my knowledge as the 'Summoning Grimoire'.
I, being the sucker for ominous names, was allured to it like a moth to a candle's wick engulfed in flourishing flame. Unfortunately, like the moth, I was burned.
Soon after I opened the pages of the book, I was appalled to see that the pages were merely blank. White as a blank canvas, as dull as bones.
Dismissing it as some sort of peculiar attempt at a joke, I strode of to oblige to my schedule.
Or at least I tried.
There was some sort of gravitating force emanating from the bounds of the book, paralyzing me to where I stood.
Suddenly, everything flashed red, blurring my vision.
Waking up from what I thought to be some sort of disconcerting, lucid dream, I sighed to myself in relief that I was on my bed...
Except that I wasn't on my bed nor was I in my house. I was in some sort of whole new dimension altogether.
Due to some grievous mishaps and other irredeemable actions, I was coerced into fighting my way out of the myriad of armies sent at my path. I was deemed most dangerous being on the planet for my doings, and I regret heralding such a title.
But what was I supposed to do? Let them kill me? My will to live override such things.
While this is of course a cross-over story, I shall not specify the universes that were cross-over'd.
For you see, the Summoner can bring forth armies or lone characters from any given dimension. Of course, the Summoner has no control of what he gets for it is random. This makes a technicality of it being plausible for this to be a cross-over of every single thing in the world.
