Serafina Pekkala's gray goose dæmon. Witches' dæmons can travel far from their humans, which gives Lyra quite a shock the first time she sees Kaisa. Like Serafina Pekkala, Kaisa is extremely wise. He is vague when he doesn't know information or doesn't want to share his opinions, and believes that the things happening at Bolvanger are evil. He magically helps Lyra free intercised dæmons from their cages during a fire drill and promises to help reunite them with their children.
