Daisy Starfall,

An eccentric and reclusive mouse to begin with, Daisy found fascination with the new druid coven forming just outside the farm in the woods. 
As a Circle of Stars coven, they're based in cave high up a cliff face where they've built an astronomical observatory.  Daisy followed them, and setup her own home in a nook where the druids regularly meet.  She has learned much from them, mimicked their incantations and rituals, and as a result she is a full-fledge druid in her own right, just without a coven.
