According to the Oracle of Snowspire, the balverine was descended from a terrible creature called the Balvorn which was far more vile and savage than a balverine. It feasted upon thousands of humans at a time. There was only one man who survived its attacks, and that man became the first balverine. Citizens of Albion are afraid of these beasts, and with good reason: balverines can infect others, turning them into balverines through a bite. Perhaps because of their terrifying qualities, some have been captured and put into venues like the Arena and Crucible for gladiatorial purposes. Their natural aggressive tendencies make them perfect opponents of Heroes in the battlefield. It is said that when a man gets bitten by a balverine during the full moon, they become the much more powerful White Balverines, which were slain in the Old Kingdom through the use of silver weapons.
