Juniper was a young mouse slave at Fort Marshank, and a good friend of Yarrow. He was among the second group of slaves to be freed, led by the mouse Brome. He later took part in a fight against Marshank, but took a fatal arrow when he stood up to celebrate. Juniper was buried on a clifftop and was greatly mourned by his friends. Felldoh swore to avenge him at the funeral, much to the disgust of Brome, who thought such remarks to not be a proper respectful goodbye.
Junipers are a family of evergreen bushes and small trees.
