Trilluna the Wain lives on the moon, Lunaria, after being banished from her home planet when she caused half the academy to fall into another dimension. This proved her wormhole technology a success, but her amibition got the better of her. Her spaceship is called the Infinite Draphly. Continuing the research on Lunaria, she was accidentally thrown into the distant past.
What are you doing here on Lunaria?
I haven't seen a new face in ages.
I don't suppose you're here to help me.
If you're not, then I would advise you to leave me alone.
Trilluna's design appears to be based on an unreleased version of the Wain petpet:
She helped to develop the Moonrover Petpetpet species.
