Aelliana Caylon, Clan Mizel is a protagonist of Scout's Progress and Mouse and Dragon.
- Tawny hair, changeable green eyes, left-handed
- Her face is thin, the bones show cleary at her collar, impossibly delicate. I can span her waist with my two hands. Her hair is light brown, shot through with gold, yellow and amber, like a perthian tapestry. Her eyes are green, gloriously so; when she is troubled or very deep in thought they seem to mist over, like fog shading the ocean. When one comes to know her, it is obvious that she is very far from frail. She has strength of purpose enough for the captain of a starship, wit, humor - and a temper. She flies like a scout and mathematics are her first and truest language. - Daav's description
