A princess from Rukiya's fairy tale whose role La'an Noonien-Singh played twice and who gave her a dog named Runa.
Princess Thalia is a character from The Kingdom of Elysian, Rukiya's favorite fantasy book. In The Elysian Kingdom, a nebula entity turns the Enterprise into the book's world, and La'an Noonien-Singh unwittingly plays Thalia alongside crewmates cast in other roles.
In Once La'An a Time, the landing party is captured in the Elysian Kingdom, and La'an reluctantly poses as Thalia, who is challenging Queen Neve. After La'an makes peace with her inner struggle, Thalia gives her a dog named Runa.
