I had a glimpse of an idea once, that I pondered for a while to make up an even larger ridiculous idea.
What if the Myth world was our own but, oh let's say, 50,000 years ago or whatever. All right, now it's modern day, and somewhere, somehow, somebody has come across the head (remember, after TFL, we still don't know where it is), and he somehow convinces the poor soul who found him to help him get a body for himself. Now, he calls upon the Leveller (yes, stretching) and now he's the leveller (You could also just say that somehow the leveller returns and skip the whole head thing). Now, we have the Leveller going crazy in modern times. The dead are walking the streets, destroying modern civilization. Modern day weapons are being used against them, however, they also have modern day weapons (Thrall now have machine guns {any idiot with a trigger finger can use them}), the Fallen Lords have modern technology PLUS their magic.
Our only hope is a small group of Heron Guards that have kept themselves alive throughout the ages and have been guarding the tomb of their king. Now is the time for Alric to awaken!
Okay, kind of hokey, but like I said, just an idea.
