Rule Number One: Don't Kill the Messenger

Evie is a messenger of the demon realm, serving under the great merchant demon, Lord Toglua. While out passing along her lord's orders she finds a small sickly creature with a bull skull for a head. She suspects it may be a fellow messenger, so she decides to take them home and nurse them back to health. All is well and dandy until Evie finds out how this creature wound up on death's door. Now someone's going to pay, because no one violates Evie's number one rule and lives to brag about it.
