Gus

Gus is one of the three main characters of the show, along with Cassy and Verne, who uses UBOS to travel to center of the Earth to stop Zarlak, a evil dark wizard.

Series
He is half Elf. He is quite confident but sometimes acts childishly. He at first looks down on Verne due to his "mortie" status, but Verne manages to redeem himself.

It is revealed in "Magical Quest" that he is related to a werewolf. Because he is half elf he is attracted to anything shiny, and when he sees something shiny, he goes, "Ohhhh sparklies". This usually makes Verne have to pull on his hood to keep him out of trouble. He has the ability to imitate voices without the assistance of magic. Gus's family symbol is a green star which is displayed on his shirt.

When his shadow is taken he acts really, really silly...

Verne
He doesn’t think much of Verne at first and just does his duty of keeping an eye on the new boy. Eventually Verne proves he is a useful ally. Because they share a dormitory they are regularly together.

Cassy
He was friends with Cassy long before Verne arrived. She has to tug him away from shiny things when he gets obsessed with them or talk some sense into him when he’s being childish or silly. And sometimes when he’s picking on Verne.

Trivia
His favourite colour is green.
