A lumin is a minor celestial that appears as a sentient glimmer of light. Earning the trust of a lumin is hard, but once gained, their loyalty is very strong. Sometimes lumins live in hallowed places, forming small swarms that protect their abode from intruders.

The Find Familiar spell can summon a lumin.
