Great chapter and a great fan-fic keep up the good work. Regarding the poll. I dont know your plans for the story (will mc stick with sam and dean or have his own journey) but if he sticks with sam and dean then go with demons since you can use it as a meeting point for them at some point. If he has his own journey then you can go with any monster (other than vamps) since not alot have been shown about them and you can just write your own progenitor (children of lilith) of those monsters. You can use vamps for the occasional meet up of mc with sam and dean since basically it’s already shown about them (besides their alphas death was sooo anti-climactic in the show). At the end of the day it’s your fanfic and you can just do what you think is good. This is just my opinion. Again keep up the good work.
