Gareth is the last Mascalian, a forgotten sub-race of humans.  He has no memories of his life prior to being found on a beach by a fisherman when he was five years old.  Gareth is a language scholar and became the youngest professor at the University Arcanum at only 16 years old.  Two years later, he is on track to become the youngest tenured professor in University history.

Gareth is a primarily upbeat, optimistic person.  He is so upbeat that he sometimes fails to notice dangers around him.  The only time he gets really down is when he feels guilty for something, whether or not it is actually his fault.  An example would be him feeling guilty for Tralnis and Henry (father and best friend) being banished from the University, even though they were the ones who demanded to go with him when he was given his impossible quest.

Gareth is instantly smitten when he first meets Izzy Morgana.  These feelings only grow stronger as the story progresses.
