Trilena Stonehill was the co-owner of the Stonehill Inn in Phandalin. She assisted her husband, Toblen, in running the inn. She was the mother of Pip Stonehill.
During a battle between the Redbrand Bandits and The Party that took place at the Inn, their barmaid Elsa was killed. Trilena hasn't fully forgiven The Party for bringing the Redbrand's attention to her and her family, and the death of Elsa.
