Wall of text ahead!!

I didn't buy a thing out of "Priscila is Seathes daughter" or " Solair is the firstborn". It is just ..... nonsense. When I saw Priscila and the 'hoard of mistakes', I instantly thought that they were "concived" by the same creature, Seath.( By concived I mean created but that word is a bit overboard since they were already there but seath, somehow, managed to turn them into their current form) That's why I believe that Priscila is the daughter of one of the Piscas, modified before birth by Seath who saw this as a new opprotunity, into her current "ghastly" form and not some kind of monster sex.

As for "Solair is the firstborn" idea, I like to believe that this is just another ray of sunshine that our fellow Dark Soulers have created to sooth their pain. Solair is obviously not the firstborn because if he, in his current strength,  was the Firstborn, then that means that the chosen undead is the firstborn, too. And the Devs have already stated that the Firstborn was not included in the game. So, even if Solair was ment to be the Firstborn in the original concept of the game, he isn't in the vanilla game which is our source (this resembles the case of Artoria's cut dialog).
