In an issue of the "Teen Titans" comic book following the events of the series' final episode, Geo-Force—Terra's superhero half-brother—makes an appearance in which he reveals that Terra, like he, is a member of the Markovian Royal Family that fled their home nation after they were both subjected to forced experimentation with a fictitious chemical called "Quixium" that gave them both geocentric, earth-manipulating superpowers. This issue sheds light on where Terra came from, in addition to the source of her powers. Geo-Force is later convinced to allow Terra to live without her superpowers in peace, and leaves without ever reuniting with her. However, how Terra got out of her stone state, who is currently looking after her, and how she lost her memory currently remains a mystery.
