[CAUTION, FIRST TIME WRITER HERE]
Not good with descriptions, but it's basically Octavia from Helluva Boss getting transported into the Half Life universe starting off in Black Mesa, the world's most prestigious research facility. Or is it America's most prestigious research facility since it's from USA? IDK
(Might update description when I get better at writing or not update at all)

Waning from "The Nothing" | Mumei x M!Acheron!OC
In the beginning of everything there was nothing, an imbalance of Chaos and existence followed after. The Gods, intending to stabilize this destruction, created the Concepts of Aspects; Space, Nature, Time, Chaos and through their collaboration and coexistence, Civilization created itself. These concepts took shape and formed The Council, governing existence as we know it to maintain balance as the Gods intended. A new destructive force has plagued the cosmos, they call themselves the Anti Matter Legion. A parasitic creation that seeks the destruction of all existence and civilization, the very drive of The Council. Are they enough to take down this threat? But if you recall...before everything, there was nothing. But The Nothing was never a silent force. The Nothing needed to exist for something to emerge, but within the Nothingness, something else emerged, or rather someone else. -------------- This might be the stupidest concept I've ever come up with and may even be considered cringe but I've been LOVING Acheron's lore and was always interested in the Aeons of Honkai Star Rail, I feel like I'm making this book out of my own entertainment but if you guys want to give it a read then please enjoy! I would like to clarify that this book won't entirely cover the universe of Honkai: Star Rail. Only some aspects will be mentioned which include the OC and the main antagonist group. © I do not own any content from Hoyoverse or Hololive, all Vtubers mentioned in this book belong to COVER and character concepts of anyone else are all referenced to Honkai: Star Rail. If any art is added into the book, IT IS NOT MINE! ©
