Interesting. When I look at this I see printed circuitry like you would find on a PCB. In which case it could represent the electrons flowing downwards into the processor which powers the shell. And the power source might be the wizard himself or his beard.

The power source is the fire underneath the shell.

Ahh. Good point! Perhaps a better analogy would be that the brain processing power is represented by the circuitry. I’d be curious to other interpretations for why it appears where it does.
