Veronica is the Archpriestess of the Chosen One.
The Chosen Ones is a group of people with a belief that "the legendary Chosen One will give them salvation from all the torment of this land" - a new religion that came about since the Invaders started to attack mankind. Their fate and goal are to find the legendary Chosen One. Because no one knows who the Chosen One is, nor whether one actually exists, they believe that they must find Chosen One candidates who might yet not be aware of them being "Chosen One," and awaken their abilities as the Chosen One through the Chosen One trial. Nothing is known about the specifics of the trial for the Chosen One, yet it is told that no one has survived it so far.
On the outside, Veronica is a kind and naive leader who guides the people to faith and devotion with the pure religious faith of hers. So naive, that she would even approach an enemy ten times the size of her to preach to them. Yet when someone refuses to believe in the Chosen One, it becomes a whole different story. It is said that Veronica's eyes give off a gruesome sparkle when she compels the non-believers to kneel and repent. There is one other occasion when her eyes sparkle; that is when she encounters a Chosen One candidate.
Veronica's faith in the immaterial Chosen One well deserves to be called fanatical - her unconditional faith has attained great power in itself and transformed into holy power, after all. As the World Tree has been burnt away, there are few Gods left who can officially bestow holy power. Thus however powerful, Veronica's holy power is a dangerous gift with its doubtful origin. Yet to the believers, there's no stronger living proof of the Chosen One. Veronica uses this 'Holy Power bestowed by the Chosen One' to propagate to the whole world, convert the non-believers, and arrest those who have escaped the cult. Recently, reports of a new Chosen One Candidate, the Guardian Knight, engrosses her attention.
