Dr. Jaeger had a gentlemanly appearance. He was fairly tall and slender, had straight brown hair neatly parted down the middle, teal-green eyes, and a thin beard and moustache. On the left side of his chest, he had a large cross scar that he carved into himself as an oath and rite of passage to join the Restorationists. He wore circular glasses, a brown suit with a white cravat and a white shirt with ruffled sleeves. He was also seen wearing a small, black hat with a gray stripe at times.
