Eldrin Gneiss is Theodore Diggers' mentor and teacher in the arts of magic. He has a strange sense of humor, which combined with his powerful and unpredictable magic, sometimes makes life interesting for those around him. At one time he was working on a Guardian spell to protect Britanny. The Guardian got out of control, and Theodore and Julia had to team up to defeat it, which they only barely did. Recently, it seems Gneiss completed work on a second Guardian- this one using Britanny's husband Stryyp as a template. It serves and protects her as loyally as the real Stryyp would.
