Noticed Krystalvix's stuff has been deleted, sources: https://www.deviantart.com/krystalvix https://www.furaffinity.net/user/krystalvix/
This isn't everything - nobody backed up his deviantart on wayback so that's mostly gone now. I'm posting this in the hopes people will post what they have on e621 or rule34.net or some booru somewhere where it'll actually be seen, instead of staying on some harddrive somewhere https://e621.net/posts?tags=krystalvix_%28artist%29+
