Leonard Chesterwolfe is a wolf first encountered by the party during the Session 1 - The Disappearances in Southaven. Drawn to Ferinthria, he quickly became her loyal companion, fighting at her side through ambushes, cultist lairs, and many other dangers.
In Session 10 - Flight and Revelation, Leonard was left behind amid the chaos of Malrith Kelbirn, the Starborn’s dark ritual. He was mourned greatly by the party. However, hope returned in Session 19 - The Verdant Reliquary when a message from Lyrian Brightwind revealed that Leonard had survived and been found.
