An introductory text to the demands of demon summoning.
"And Lo; today Alea Waxes, and she shall blesses us. For soon a great change is upon us, for soon our beliefs shall be hallowed! We as a group, we as a people, we as a religion, shall be acknowledged. Our efforts shall no longer be in vain!"
--The Prophet John, Sermon to the Capitol
"And Arathinos brandished the Foe-Reaper, and let loose a battle cry. He stood, with rain pouring out of the heavens, on a mountain of bodies. The rain washed the blood through channels in the corpses. Arathinos raised the Foe-Reaper and saluted the fleeing enemies before him, as lightning crashed around him.
The Foe-Reaper is a great blade. With the years spent in Arathinos's hands, it has taken up a myriad of powers. And most prominent among those powers is dramatic effect. What is more morale-sapping than seeing your enemy with a backdrop of lightning, as if the arrows of the heavens stand with your foe?"
The founder of Procrastinamancy was a man called Frederick Johnson. A normal guy who grew up in a place without Mathom, Fred had one "flaw." It was procrastination. Fred took the art of Procrastination and turned into magic.
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?
