Ah, the creatures of the night - Vampires! Injecting a bit of spooky into our otherwise mundane world. Typically represented as immortal beings, their activities are largely shrouded in mystery and legend. They feed on the life essence, typically human blood, and are often depicted as hauntingly beautiful and irresistible to humans - making the act of feeding somewhat easier. Usually nocturnal, they rest in coffins or isolated places during the day as sunlight can harm or kill them, according to much of popular folklore.
