A poster above mentioned that when protagonists lay plans, they are obviously going to fail.
I think this applies not just to the protagonists - but to Serini as well.
It's pretty obvious that there's no way team evil are actually going through all of Serini's traps in The Final Dungeon.

Also let's face it, it's far too early in the book for the actual final conflict with team evil to happen. Too many open plot threads. So there's no way team evil goes into conflict with the heroes yet.

At some point something is going to happen to allow team evil to get past the defenses and put the heroes on the run again.

I think the fight with Calder will be the instigation of it.
Too early to guess how, but maybe he'll chose to runaway (he clearly won't surrender again) and smash through the walls? Trigger some other defense? Blow stuff up?
Do something near the threads of creation that would put a serious dent in the place?


Either way, something will happen to shift the entire situation of who is in control and the path to the gate.
