Totally not a vampire
EDIT: P.P.S, As you may have noticed, my two stories feature pretty much exclusively human characters. I'd love to remedy this, but my knowledge of types of creatures that fur affinity posted stories might utilize is woefully inadequate for any storytelling. Is there some sort of wiki or website where I might learn the various species, the differences between classifications such as anthro and feral, their attributes, tendencies, commonalities, and how to best implement them into a story setting? Is there some sort of "furry-verse" with established rules, magics, and species I might read about?
Honestly, you can kind of make up your own rules. There are some furry-based universes out there - there's Star Fox, for example, though the only non-mainstream one I can think of off the top of my head is Vilous, where the Sergal come from - but it's not like there's one big cohesive universe that all furries come from.
There's nothing wrong with using human characters, though! I do it all the time! :3
