A man dies in a plane crash from a supposed terrorist attack. A mysterious... Devil reincarnates him into a new world and gender bends him into a female.

It looked to be your standard fantasy world at first, but as Arpious traverses farther into her journey, she finds out that she might not be on a planet.

She discovers many secrets that are unknown to her fellow monsters, through the help of her comrades, wives, and even enemies?

She learns that the sky is fake? There are worlds right under her world? How is that even possible?

Spirits instead of gods? Where the heck is she?

'Why' does one strive to attain power?For what reason does one endure various rigorous trainings, endure the bruises and the batterings, and go ahead to drill their soul and body into perfect shape just to become stronger?Those ridiculously overpowered, god-like monsters that walked the Earth knew, because they never stopped training.But I didn't know the reason.Why, one might ask?The answer was quite simple, really.I had no desire to 'know' the reason, and I had no drive to discover the 'why.'It was because my circumstances gave me no reason to become stronger. And stupidly enough, I greatly believed that I was strong enough to fend for myself.But boy was I wrong.Fate punched me in the guts, and proceeded to give me very, very good reasons to abandon my narrowed mentality and strive to become stronger than I thought I was.And those reasons multiplied by the day.As I ventured out of the dreary slum-like backlands that I grew up in — diving head first into the wider world overrun by monstrous aliens, insanely advanced technology, and humans with supernatural powers — the initial 'why' had grown to become quite... numerous.So come. Come read my story.And see how I crawled out of the depths of the dejected Island called the backlands as a nameless underachiever, and grew to become a.. tether to the entire universe.Come read how I came to be called...The Twilight of the Vast Expanses.

I came from hell, looking for redemption! –“Revelation”
…………
What is redemption?

It’s like our clean birth, contaminated by the dust of one life, and then clean death.
Well, this is just a story. …
