Fall of Equestria: The anon king's plot
Draft:
ch0: begins with mysterious figure talking to 'you', treating this meeting like how every pokemon game starts, with mystery guy discussing about the world you are going to be in, introducing themselves and getting to know you, all vaguely. ('guy' has odd chat with you about how they 'need' you to do as much discourse in the 'position' they are putting you in, while taking care of an individual called discord.) After vague introduction, you awaken in a bedroom.
Ch1: awaken in a fancy bedroom, learn that you aren't human anymore, and is currently a king with some kind of harem. A guard interrupts your personal thoughts to reveal more about your situation, unaware that you aren't who you should be. You do your best to play along and it works. Upon seeing this, one of the slaves (which you learn her to be called luna) tries to make sense of the change of behavior. You then explain your situation, and while skeptical, she believes you. You oddly give a quick response that you have a well conceived plan to help save her, her sister, and her people from the caribou, all while playing the fool.
Ch?: discover that the true villain is the 'creator', a somewhat god-like deity above all other characters who has been trying to manipulate the worlds in his favor. Though some have worked, others have been failures, and those failures are growing. This villain creator (NCN) has sought to make entire universes an entire pile of sex and debauchery with male superiority over females, in which 'you' find out too late? or just find out in general before returning home. Thinking it was some f**ked up dream or something. It wasn't.
