Illusia

Illusia was created in 1944 by the Finnish author Yrjö Kokko for his fairy tale Pessi and Illusia. In the story, Illusia is a rainbow-dwelling fairy who falls in love with an initially-pessimistic troll, appropriately named Pessi. The fairy tale was adapted into a movie in 1984 and is also a ballet in Finland.

Illusionist Criss Angel named his daughter Illusia Angelina.
