Vampire - No Bones (Patreon)

I previewed this artwork years ago on bogleech.com, but I never explained what exactly it was!

I can no longer find the same sources, but I'd read about a vampire simply called "no bones" or "boneless," which was said to have been crafted by the devil himself out of human flesh and described as resembling a wineskin that can "stretch out long or compress into a ball."

This is really almost a perfect description of a leech.
