Ruby is the second of her nomcromancer's attempts at creating the perfect evil minion. Once again he failed, creating a sweet and sour nom that would never hurt a fly! Frustrated with his perceived failure, he kept Ruby in a dark basement for some time,  permanently harming hsr vision and leaving her mostly blind. She and Cerus escaped their nomcromancer together.

Despite her sour flavor, Ruby is a gentle soul with a loving heart. She and Cerus (om25) consider themselves siblings.
