Traa is an estate in Peachtree Province. During the Detinan Civil War, it was seized and burned by Detinan forces during Hesmucet's advance on Marthasville, several weeks before that city fell. A daughter of the estate's lord was staying in Marthasville when the city fell and she attempted to flee the city and return home. She was mockingly informed by Thert the Butler of Traa's fate, but insisted that she would rebuild it.
Traa is based on the Tara plantation in Margaret Mitchell's Gone with the Wind, and the young woman promising to rebuild it is presumably based on Scarlett O'Hara.
