I've considered the possibility the moons' sway over Nir's tides speaks of Lorkhan's silent dominion over the seas. Legend has it the Maormeri king Orgnum is the serpent of Satakal, and his race are not only maritime, but deeply invested in serpent magics. I'd like to hear your thoughts about the Missing God, in body the moons, and if you think their twin hold on the tide is evidence of the god's power over the sea. Also, could King Orgnum actually be the Serpent of Satakal, waxing younger as the moons decay, possibly deepening his mystical control over Nir's tides.

... Do we even know if Nirn has tides?
