Valoria Gribbon

Valoria Gribbon is the chemistry teacher at Teras High School. Able apparently to digest virtually any chemical compound—and relishing their varied flavors—she often drinks down whatever's left after a typical lab class. Mrs. Gribbon likes to think of herself as being something more of an expert in chemistry than she really is, and passes up few opportunities to question Niamh about her father's work, often offering advice and dropping hints as to her desire for a tour of the Pretorius Technologies laboratories.
