Professor Glaze Garnet is one of the lead researchers involved with the sphere sequencing operations of Blue Shelf, and for a time was Doctor Bellesmith's direct superior. His work was to attempt to find a way to open the machine world beneath Blue Shelf vicariously by accessing Rainbow Dash's memories. However, after Prime Enforcer Shell took effective command of the operation, he was forced into hard labor on Black Level with the others. It was presumed that following the destruction of Blue Shelf, he managed to escape west to safety.
In Innavedr it is revealed that he was a double agent working for Nightshade Industries, and using the information stolen from the Blue Shelf operation to further Nightshade's own sequencing work.
