Human: Write a description for a fantasy rpg of Gerald Svelger is a Gnome male that lives in Guttertunnels. Assistant: 
Gerald appears as if nothing could harm him; his gnomish features are unmarred by anything other than regular exercise and good eating habits. This apparent indestructibility masks a sinister personality. His face can be stern, but when he smiles, it lights up like a child's. His long mop of red hair and bushy eyebrows give him a youthful appearance, despite his middle aged frame. He is dressed in a tan shirt decorated with brightly colored geometric designs, tucked into khaki trousers.
