Dr. Vickery is the Astronomer Royale, or the official astronomer for the British government. When Rooke visits him as a young teenager, Dr. Vickery introduces him to the possibility that Rooke isn't necessarily an extremely abnormal individual. Like Rooke, Dr. Vickery is awkward and avoids eye contact, and cares more for the stars than he does for people or for anything that happens during the daytime. While with Dr. Vickery, Rooke first reads about New South Wales. Dr. Vickery convinces Major Wyatt that Rooke should be the official astronomer of the First Fleet, and asks that Rooke record a comet in the southern hemisphere.
