Error always knew some things where off. He knew how to create things he had no memory of learning how to. He always felt off. It hadn't started off with a bang, in fact they had started with the whisper, and it had come over time. Over observation. Until he finally realized, exactly what had been done to him, and the full extent and reason of Fate's hate towards him. Balanceverse - My new AU created with @gdesertsand, our new baby Inspired by Harrish6, Healing what has been broken.

So. People have been asking about the anatomy of skeletons in my books and sometimes monsters in general, but mostly skeletons. I'll be addressing the topic here. I won't force this on anyone, but if you want to use it, tell me and credit me! Anyway, you can ask me literally anything and I'll do my best to answer! The first chapter will be basics, and I'll continue from there. But yeah, this is a book now.. Sarah, I hope you enjoy; I know you've been asking so much. UwU
