In Star Ocean: The Second Story, Heraldry is the form of magic used by most wizards. The system revolves around the use of certain designs which have been found to have special effects, known as Crests. The basic Crests were revealed to people who prayed in shrines dedicated to the god of creation, Tria.

When placed upon equipment, Heraldic Crests bestow properties such as causing fire; when tattooed onto a person, Crests' effects can supplement and enhance mental powers -- abilities normally too weak to be of any use can be developed into spells.

Those of the suspiciously elflike Nedian race are masters of Heraldry, not only having knowledge of some of the most powerful Crests possible, but the ability to draw upon the powers that lesser Heraldic patterns attract without getting tattoos.
