Burning in their chest told the leviathan it needed to breathe. With the aide of swim bladders and many fins the great serpent rose from the depths where it preferred to swim, their body adjusting to the changes in pressure as it ascended.

Warily, they surveyed the ocean around them relaxing only once certain they were alone.
