Henrietta

The partner of Stilda in the Copper Carters Consortium. Her family had fallen to misfortune, partially due to the Gilded Throne, leaving her with little option than to join them as a guard for work. She currently has two kids.
After the OsterRat' heist of treasures from the Gilded Throne, Henrietta was supposed to meet them in the morning to travel to the Godstear Mine. However, she had received a letter written in Tyffany's hand indicating that she should wait and they would head out the following day. This deception lead to the changeling Faney taking her place travelling with the OsterRats, unbeknownst to them both.
Her surprise at the deception and seemingly honest interactions with Stilda, their children, and Tyffany, makes it seem like she was not in league with Faney.
