Biography
She is the sister of the titular Geronimo Stilton. She once went to Mouseford Academy, a school. She was reckless, but a great student. She eventually graduated and became a special correspondent for The Rodents Gazette, the most famous newspaper on Mouse Island run by Geronimo.

At one point she came back to Mouseofrd Academy to teach a journalism class. There, she met five mouselings: Colette, Nicky, Pamela, Paulina, and Violet. They were all very different, but they became friends with each other. Soon, a mouse named Hans Ratson disappeared, and the mice ran down the cellars to search for him. After a failed attempt, the five mouselings came again and scampered into a stone dragon's mouth, only to fall underground where they found Hans Ratson, who turned out to be the journalism teacher named Bartholomew Sparkle, who wanted to search the cellars.

After the incident, the mouselings named themselves the Thea Sisters. Thea left, but occasionally saw the Thea Sisters, who would go on adventures and solve cases and mysteries like Thea. To this day, Thea goes on adventures, usually dragging Geronimo into them.
