Corinna is the daughter of Thericles, who works the vineyards in The City of Estoria. Her friends were lured into the temple by a beautiful woman named Demetria, who promised wealth, beauty, and fame and while Corinna was suspicious she ended up following them to nsure her friends were safe.
For three long days she stalked and scouted the ancient temple her friends were taken to. Braving the temple she was attacked by goatlings that pursued her.
The Heroes of Thylea rescued her and she helped them to save her friends from the temple.
Eurytus delivered her a letter from Castor Catsakis which seems to ensure her a place in The Academy of Mytros.
