Something to watch out for this Valentine's Day, a predatory pair from illustrator Collin M. David (ResonantFish).
The Cardiovores appear once each year, and always travel in pairs. They are naturally attracted to those who are in love, as these couples are more delicious than others. Once their prey is captured, The Cardiovores consume them, heart first. Once replete with food, they slither back into the depths of the forest and burrow into their subterranean nests, keeping each other warm.
