Shattered Glass is a member of the Doctor's Prydonian tribe. He was once the Doctor's mentor, and now possibly the mate of his daughter of Swirling River, as he hangs around her more than any other cat.
- He is named after the attack on the Frozen Allegiance (when it first formed and started its attack on Prydon), called The Attack of Shattered Glass, but he says he was named after the sound his claws make on freshly laid snow.
