Tall (men were taller in the 16th century than the 19th), with straight dark hair.
“A man—dark hair, blue eyes [cut]. He was wearing a fur coat, of all things. Wasn’t he sweltering? He didn’t look like it… Underneath he wore a black shirt and pants of ambiguous style, with what looked like black combat boots and a big black belt. Despite being somewhat death-metal, there was an almost medieval aesthetic to it.”
