War Vampire

"These bats bred for one purpose: for war."
—Legolas about the bats

So I had this thought of drawing a humanoid vampire woman in Dol Guldur trained in swordplay in part thanks to Thuringwethil who is said to have been a Vampire in Middle-Earth. Not much else is mentioned about them in the lore of Middle-Earth, but there's this hunch that J.R.R. Tolkien's vampires were not really vampires but just sentient bats like how his werewolves are actually big wolves with the faea of fallen maiar in them.

Thuringwethil may well have been a maiar, but she may also well have been just a big bat some sources claim... but forget it's a vampire woman of Dol Guldur wielding knives, this should be a non-canon character for the Battle of The Five Armies.
