A glint of spectral fire.

A single wisp of fire that orbits between all three of your quigar's eye sockets, changing shape/location moment by moment.

• The fire can glow softly if desired.
• It can be depicted as floating between multiple sockets, as long as it's clear it's one flame, and not multiple.
• It can also be solely contained within one eye, and the others may be hollow.

If you're unsure if your idea is valid, feel free to ask.
