A stirge is a vicious blood-drinking creature that resembles a monstrous cross between a large hummingbird and a mosquito. This creature lurks in forests, caves, and swamps until a living creature passes near. It then flies down and attempt to subtly attach itself to the creature and feeds off its warm blood.

While one stirge may not seem to be a threat, these creatures often cluster in large swarms, which can quickly slay a creature from all the stirges feeding at once on the same body.
