ok guys. here we go.
we know that the leveller comes in the form of an evil that comes only every 1000 years
we also know that his coming is associated with a comet that appears in the sky.
and we know that when Wyrd made the world, he was divided from it and his dream shattered, leaving him powerless to controll its fate.
so suppose that teh comet is actually the reflection of the world of the dead that appears in the sky and promotes the growth of dark sorcerors adn the creation of undead.
now here is the catch. look at the dreams of wyrd that we have found. The dream of unlife, teh dispersal dreams, and all of the other dreams that the avatara use in battle. now if these are the dreams of wyrd, what makes us think that wyrd was a nice god. or a good god. we could look at the creations of wyrd. humans, skrael, fir'bolg. with our nature promoting wars and death and domination over one another. so, what makes us think that humans as well as the other wyrd races are not evil as well as wyrd himself.
in this case Nyx would have been the good person. the trow, the perfect beings, no lust, no wars amongst each other. only united against other races.
so here we go. this would mean that while the world i mentioned earlier "rubbed" the evil sorcerors came to power, and wyrd somehow came into the world, taking the dtrongest physical form he could remember. the hero who defeated him. he would unite the evil sorcerors(the ones that knew he was the evil god) and attack the humans and destroy the world he created in an effort to destroy the failure that was his world, when he could no longer controll it.
unfortunatly as the worlds began to separate, he weakens, and loses power, and then is defeated by a champion of the race he wishes to destroy. and then he would have his spirit ripped from the earth and would have to wait another 1000 years to come back and start the job over again.
