Life as a street urchin is a pathetic existence indeed - and Me’fiante has it worse than most. In a back-alley underworld filled with trickery and subversion, the ability to sense lies is often more of a curse than a blessing.
...and the crow spoke of an age of eternal night and of the devouring of the sun. The sea will boil the blood of the maker, the sky will flood with a dark pestilence raping the land of all its bounty, and the mounds will break loose what death had acquited… So is the propecy of the end.

After the PCs defeat (or force the rapid retreat of) a villanous necromancer/demon summoner, they discover a book. This book outlines how to summon a demon whose power increases according to the size of the summoning circle used to summon it. And after the PCs examine a map of the country, they find that the layout of the cities and roads match up with the required summoning circle. In fact, the final road that would complete the circle is currently in construction.
With anyone who can find out about the circle and the ritual to summon the demon able to somehow make the final road/line, and destruction of the cities and roads currently in existence out of the question (unless this is an evil campaign- that removes the moral quandary), how are the PCs going to solve this problem?
