Took a while to figure out which one was yours (Black Lotus seems to be a popular title). It's an interesting teaser, telling you nothing but suggesting so much. My only issue is based purely on word choice, simply because you chose words that I would not. That is just a difference in writing style, rather than a true criticism.
I'm curious to learn the mean and the power behind the lotus symbol. The suggestion seems to be similar to vampirism but that is neither confirmed nor denied. You have piqued my interest and that is hard to do with a period piece.
