Seers are passive understanding classes. Since they only understand their aspect thoroughly, Seers are unable to change or affect their aspect in any way. But, the Seer’s inverse is the Witch, granting them much power and control over their opposing aspect coupled with their already lengthy passive understanding of their own aspect. The way Mages and Seers function is through their inverse: understanding the “mold” that their aspect takes the shape of, they accomplish a change in their opposite aspect to fit with this mold. It is in this way that Seers such as Rose or Terezi effected great change in the way of their opposing aspect, all the while helping their team with their already-present understanding of their own.
The Heart aspect is all about the self: who you are and what you feel independent of what you do and think. Heart is centered around the “self” of things: core, the inner nature of things, and individuality. Heroes of Heart are said to “walk the path of self.” Heart deals with what you feel and what you are, and tears down the facades that its opposite Mind uses to conceal and deceive. Where Mind favors thought and action, Heart values the worth of people and things as they are, as opposed to how they could be. It deals with one’s inclinations and feelings towards certain things, emotion, and truth of being. Heart represents the individual, our inner passions, and what defines us as people.
A Seer of Heart then would have an extensive and passive knowledge of individuals. They would know their inner feelings and their beliefs separate from how they outwardly behaved. They would comprehend their own identity as well as the identity of those around them quite well. The inverse of Seer of Heart is Witch of Mind. The majority of the Seer of Heart's influence would happen through its inverse. Active manipulation of logic, knowledge, and general facades. All of this would be moved, changed to fit the mold of the Heart, allowing for individuals to function based upon who they truly are and how they truly feel without regard or at least with less regard to logical planning and hiding the self.
