Nathan and Polly Johnson's House

Origin
Nathan and Polly Johnson were free African-American citizens in New Bedford, Massachusetts. The Johnsons were wealthy citizens, Nathan being a pharmacist and Polly being a candy maker. They sheltered many escaping slaves, including Frederick Douglass, the famous abolitionist.

Effects
When the artifact was still functional it would allow the user to flee from the attic door to another house that Douglass stayed in. The door would active at exactly 10:39, turning the attic door into a direct passageway to the attic door of the other closest house, which would then be gateway to the last house in Bedford.

Collection
Sadly, two of the houses were destroyed, rendering this artifact unusable. While chasing a perpetrator, Jack and Rebecca came across the house. After the suspect escaped through the attic door he then lit a fire at the second and third house.
