Castle's Pet

That thing here took me almost three hours to make in total (breaks are not included), but it was worth it. I just love it how Vile is stalking everyone in the background. Hi Viley! Whaddup, ya creep? XD (Here's the link for the sketch-thingy.)

If you still don't know what Castle's Pet is, then let me make a short summary about it... By the way, that book had started the #ShoeTheTape trend. Proof can be found at the end of chapter 3 because that was the one sentence that basically created STtale. And yes, Vile will be part of the book too, just not now since it's way too early for him to show up.

Castle's Pet is a X Reader book where you, as the reader, are being shipped with the bad guys of the multiverse. Some of the villains may not seem evil enough for the liking of most people but they do play their roles more in the background by either assisting in Nightmare's castle, doing something in their own AU's or just simply keeping hostages/prisoners to torture on. In the story are the villains decreasing their murders and destructions to a minimum, making the Star Sanses force themselves to find out what they are trying to accomplish with this tactic. Your name is (Y/N) (L/N), a 17 year old girl, and you fell down Mount Ebott when you were 15, so you had lived almost two years with Toriel, your "mom". However, you get captured by the bad guys just about half an hour after meeting the original Sans from Undertale, your "home universe". How did the villains find out about your existence? Well, a cloaked man told them about you and about how "powerful" your SOUL is. Is it really that powerful? Nonetheless are the bad guys starting to act weird around you, one by one within your first week at Nightmare's castle. And even though they call you the castle's pet, why are they treating you like you are a lot more worth than that?
No matter how much you like it there, mom will find and rescue you from your kidnappers.
