Calypso

Calypso is a crow. He travels with Magpie Windwitch and is like her brother. He is the leader of the crows and has a chip in his beak that makes it seem like he is always grinning. He often calls Magpie 'Pie and feels very responsible for her. He takes long-life potions given to him by Magpie's mother so that he can keep travelling with Magpie.

Calypso states that Magpie is "Still a sprout" whenever she insists that she isn't. This is because he doesn't want to think of her growing up.

Calypso seems to be the leader of the crows.

Magpie:
She is sort of like his sister, or little girl. He treats her like a "Sprout", but she loves him anyways. She calls him her "Bird brother" in Blackbringer, Magpie wears a skirt made of all of the bird's feathers.

Other Birds:
Calypso seems to get along well with the other birds.
