Regarding the coming denouement...
 

Brian, should be see the White Mage twist as the climax of the story, and the rest will be a denouement, and THAT'S ALL, just a wrap-up, or are there anymore interesting little plot points waiting for us?

No specifics obviously, but is there anything left to look forward to besides a strict wrap-up?

Out of curiousity, has Brian ever spoken on the 'Matoya never gave the Light Warriors the antidote to the Nightmare Juice' plothole? Or is it one of those things he conveniently overlooks each time it's referenced because it's something he hoped no one would notice for a future plot twist?

I think it's implied that they got it at some point between 311 and 314.

They haven't had the nightmares since then. That works as proof they got the antidote for me.

I don't believe this.
 

I am far more interested in longstanding plots like the Dark Warriors and what will happen to the world now that the orbs of light are gone.

The Dark Warriors are probably huddling in a dark corner, together, possibly naked (Would anyone be surprised?), still fearing Sarda's wrath.

EDIT: The Orbs of Light could be replaced by the light bulbs BM stole at the beginning of the comic. The world is too stupid to know they're not magical.

Maybe it's not too late for an 'everybody dies' ending...

Except that Brian said the "everybody dies" ending wasn't going to happen. Although, actually, he specifically said it wouldn't be an ending like Nuklear Age's... so maybe I'm wrong about that. Hmm.

Personally, I'm curious as to how Onion Kid grows up in a world no longer terrorized by the Light Warriors. There's bound to be something happening to them soon... right?

Kid's at a wizard school. He's geting more powerful every day while the LW are stll completely deleveled, odds are they'll avoid him for fear of being slaughtered. Besides, they're already past the threat of Sarda, why risk facing anouther mega powrful wizard.
