Biv is usually undetectable by all senses expect hearing and touch. He becomes partially visible thanks to the unintentional interference of his platonic friend Anna, who disrupts magical energies.
Biv later participates in the running of the Mosaic Wellness Center, which becomes a haven for supernatural beings who need to turn their life around. For example, he becomes friends with Trots, a demonic puppet who no longer wishes to harm others.
