Catana was once a lonely stray in her mortal life, beloved by the residents around her. One day on her daily prowl, a trio of vile humans took her. They tormented her, and cut off her tail, leaving her for dead. Upon her deathbed, she cursed those mortals, calling attention to the Dark Lord who pitied her. He took her soul, reshaped it, forming two tails for her. Her rage and anguish manifests as three cursed blades, one for each scumbag who abused her.
