The flapping of leathery wings fills the air around this gaggle of imps, each of the fiendish little creatures scrabbling and clawing at one another in a sea of flailing limbs. Even with the never-ending infighting between them, when left masterless and gathered together in great enough numbers they are a force to be reckoned with. Fortunately it is incredibly difficult for a group of imps to focus and their goals are short-lived, usually involving inflicting as much pain and acquiring as much wealth as is momentarily possible.
