Zindle is the crew's bard, unofficial historian, and self-appointed morale officer. He knows a song for every occasion and isn't shy about performing it at full volume in the middle of the night.
Zindle grew up performing for coin in a travelling market and never quite stopped moving. He joined the Zephyr's Oath looking for material for his "great sky opera" and has been collecting it ever since.
The crew tolerates him mostly because morale has measurably improved since he came aboard. The cook has asked him to stop singing during meal prep.
