To the Camarilla of Chicago, MacTavish's name is spoken like he was the boogeyman. Some kind of ex-military commando he patrols the outskirts of Chicagoland and ensures that Anarchs are able to travel unmolested.

Duncan is an unkempt and dirty white man with a mop of shaggy, matted brown hair that has spent too long inside helmets and balaclavas, and a beard containing almost as much wildlife as the average woodland. His cold, gray eyes are permanently bloodshot, and this is more pronounced when he is well fed. He is well built, tall, and has a scowling face at rest. His voice is rarely raised and almost never shows a flicker of emotion.

Ordinarily, Duncan remains in hiding and wears camouflage paint to hide his appearance. He has, at times, been mistaken for an agent of the Second
Inquisition due to his military garb and equipment. Of particular note is that, despite his many murderous and violent acts, he shows no animal features of
any kind, normally well-established among his clanmates. The wise among the Kindred realize, to their horror, that this implies that Duncan has never
been out of control, even while murdering people.
