Priest Franz:
There's no doubt the monsters who followed you are manifestations of the evil power of Shilen. Note how different they were from other monsters you've encountered in your travels.
They must have been seeking the Book of Seal. They want the power it offers...
Do you know what this means?
It means the Fourth Seal has been broken! That's the new power of Shilen...
And I believe there's an evil plot of the Dusk called Embryo working in the background. They want to dominate this world by gaining control over the power of the Seals.
Keep listening.
