Dastardly Duchess Mouse
A great many sinister plots have unfolded in the Great Hall over the years and somehow this callous and calculating mouse always remains unscathed at the centre of it all. She spins a web of deceit so intricate throughout the Castle in the Clouds that even her spies have spies. She is so staunch and stoic that if she so much as raises an eyebrow in your general direction then it's already too late!
