The Merlin is described as tall with broad shoulders. His hair is long and white as is his beard. Since he’s in charge of the White Council. I wanted him to have a dignified look to him. So I mostly looked at pictures of Christopher Lee. However, I didn’t want him to look too much like Christopher like portraying Saurmon, since the Merlin isn’t a servant of evil as far as we know. So I mixed in a bit of Tarrlok from Legend of Korra since they are both slick politicians.
