Siberia

Gilderoy Lockhart was inducted as a member of The Order of Air Voyagers for Intrepid Wizards as he reached Ouagadougou, the furthest most point in Siberia.

Behind the scenes

 * Ougadougou is in fact an African city, possibly evidence that the document certifying Lockhart's induction as a member of this group was a forgery, as Siberia is a north Asian region controlled almost entirely by Russia.

Appearances

 * Harry Potter and the Chamber of Secrets (film)
