I have been thinking again

Disclaimer:
This is of course wild speculation and I suspect you will all find great flaws in my argumentation (I admit that it is quite far-fetched). I tested some of my ideas on the people who attended our Swedish Elohim-coffée, but they were too polite to contradict me…
In chronological order:
We all know the dangers of the 7th ward, but surely someone must have given it a try before sealing it of… Since we encounter the name Damelon’s Door in there my guess is that he led an expedition there, made a crucial error and sealed the place off. It might even be so that Damelon himself took a sip, and managed to break “the Law of Parallel worlds” – thereby making it possible to summon people from another world (surely there must have been a law against that?)… If I take this idea further I guess that someone was summoned – someone that must have had influence in the naming of Kevin (his mother perhaps? Or grandgrandgrandetcmother…) – why else this name?
Then there is the eternal, and perhaps not so fundamental, question of what Foul called himself when he infiltrated Kevin’s council. My guess is that it is something in the old tongue – perhaps either Ridjeck or Thome.
And last: another question that has annoyed my brain. Where did everybody in the Land gain the knowledge of the White Gold? From Seers and Oracles? Or is possible that there were White Gold summoned earlier and that it partook and perished (possible?) in the Ritual of Desecration?
All right folks - what do you think?
