Vienna is a sorceress and the main antagonist of Return to Numberland.


Vienna is goal-oriented, determined, and hard working. She will do anything to get the title of Prince of Numbers, even to get rid of Zilch.


Vienna is a grey-skinned troll with dark green hair falling to the top of her back. Where she grew up, Vienna has never heard of hair products. She has dark green eyes.

She wears a green tunic, black-green pants, brown boots, a navy blue cape (sometimes), and brown vambraces. She carries a bow, a quiver full of arrows, and a book of spells with her.
