Harriet Tubman, aka Aunty Minty was a character in The Trap Door. She was a Hystorian and an abolitionist, as well as Kissy's aunt and therefore Riq's ancestor. She, along with multiple other Hystorians, was trapped in Thomas Garret's house, which was taken over by SQ, although she was able to escape. After the Civil War, the trio visit her house, where Harriet Tubman tells them what happened during the War and the effects of fixing the Break.
