And as for my contribution, i shall offer you three offerings of three differing make. A CYOA, an original and a fanfiction in that respective order.
1.Metahuman inc(CYOA)
-If you ever wanted to control a megacorporation that deals in technology of both scientific and magical origins then this is precisely a game for you. Also, did i mention that you can become the chosen of a certain eldritch forces that will turn you into both their herald and the most powerful being on earth all at the cheap cost of letting them in and have them and in turn you become the ruler of the world?
2.Lord of Undeath (an original in RRL)
-Now i know what you're thinking, "Hey, isn't this just basically overlord's ripoff?". But let me explain, this guy is basically Ainz, i can admit to that, but with a certain twist. He doesn't have that annoying inner voice called humanity in there. He is what you would truly call a lich, fully equipped with a cold hatred against all things living and powerful magic of fire and death at his disposal, this guy is what comes to mind when the word "Lich" is mentioned. Although he is a bit underpowered for now, so keep that in mind.
3.Black ink, red rose (ff.net)
-Remember ginny who's only role is to be hypnotized by a book and become harry's wife with neither rhyme nor reason? Me neither. What this offers though is that nameless, faceless, and unremarkable non-amoral NPC be turned into a magical right hand woman of lord voldemort, ready to commit atrocities at the drop of a hat.
And that's pretty much it. Though i can't help feel that it is a bit lacking both in flair and in quantity. Regardless of it, i shall wish you all a good day (or night depending on which outermost crust of earth you're located now.)
