Has anyone ever wondered if the Water is somehow finite and distributed amongst the Waterbearers? Could Meppa be all the more powerful because he's the last Cishaurim? Pstatma tells Meppa that he has an ocean of Water in him. Could that be because he has all the Water, so to speak?
ETA: Also...riffing off of the idea that Moe/Mallahet was to the Fanim w/ Kellhus was to the Inrithi....
Hifanat (sp), the Cish who approaches Kellhus at Caraskand, says something like "we see you, all of us that follow Him, those w/ the 3rd Sight." That's paraphrasing; not the exact quite.
But if the 3rd Sight is just the way that all Cishaurim see...could Moenhus have not just controlled a "faction" within the Cishaurim as Kellhus speculates but all of them?
