Vincalis the Agitator is set one thousand years before the events in the novels of The Secret Texts series. Vincalis the Agitator is the story of a young man, Vincalis "Wraith" Padeuay, from the wrong side of the tracks, who befriends Solander Artis and Amaran Dolassa, children of the city's ruling wizards, the Dragons.
When Wraith and his friends learn of how the Dragons maintain their magic and city by enslaving, brainwashing, and taxing the souls of the people, they organize public nonviolent protests. The Dragons immediately have Wraith and his friends arrested and imprisioned, and several of the prisoners are executed.
When Wraith finally makes his escape, he finds that his one true love, Amaran, has pledged to marry another. Feeling lost and furious, having suffered poverty, deprivation, humiliation, and imprisonment, Wraith recognizes within himself a compassion for humanity and a passion for justice. He creates his alter ego, Vincalis the Agitator, who writes subversive materials and helps found the rival wizard group, the Falcons.
In the end, Vincalis and his Falcons must defend humanity against the Dragons and the dangers that accompany a war of wizards.
