Is there a vampire-like race in No’va? No. But I have had ideas about a race that once were feared by the living due to their blood-thirsty nature. It’s not until later when a new leader takes over that he realizes they’re wasting precious food by ripping into their victims and letting them die when they only need a few drops every couple of generations.
In steps the new, sophisticated being (unnamed) who dwells in decked-up caverns and ensure their selected “honored” guests that they will once again walk out to see daylight. The guests are dined and wined and pleasured beyond their wildest dreams until they are at ease with what is about to happen to them. The reason is fear. Fear petrifies the blood flow. Changes the taste. They want that fresh, succulent dip of ruby red, like fine wine to the tongue. Once they have it, the guest is free to leave.
I don’t plan to develop this any further. Just a passing thought.
