Yala is the child of Sydon and Lutheria, named for the original Yala that the Twins captured and slew in the first war of the Titans.
She favours her father's side and is known as the Empyrean of War. Following the exile of Gaius, she is also now the head of the Order of Sydon in Mytros.
The Oracle's Chosen first met her atop Mount Volkan, as she appeared in a flash of lightning alongside the participants of Capriolé from Praxys and Themis.
