Thalia

Thalia is a Greek name associated with flourishing or blooming. Greek mythology uses it for both a Muse of comedy and pastoral poetry and one of the Graces. Those are separate mythological figures sharing the name, rather than one character with every role combined into a single biography.

Thaleia is another rendering of the Greek form, while Thalie is a related French spelling. The name also appears in the Percy Jackson stories, and singer Thalía provides a modern musical association. Pronunciation can begin with an English th sound or a t-like sound depending on language, so the intended version is worth introducing clearly.
