Sea Arkady Leviathan (HR) (Patreon)

 Commission for LightningDragon of their dragon taking the form of a Sea Dragon Leviathan from  Subnautica.  Making a little lair for himself in a pocket somewhere  within the Lost River caverns (Perhaps in one of the unexplored bits that may have once snaked under the Dunes or Mushroom Forests~)  he's dragged a number of unfortunate Reapers down to his home away from  a home to devour and digest, though his latest catch took the form of a  "fellow" Sea Dragon who had stumbled into his territory without  formally introducing himself.  It was a mistake that one way or another,  it wouldn't be making a second time.
