In the great lake of Ture are hundreds of islands of various sizes, and not all have been completely explored by the Modern Races. One such island, with rough and craggy coastlines discouraging landing, is quite remarkable and worth a visit.
Another continuatio of the heroes’ journey through Daemonland.
An ancient spirit known as the Elephant God said to them “Thou hath defeated me, and thou shalt have thy prize: All the valleys and forest beyond yon cliff art for thou and thine.” Having beaten the not-so-malevolent spirit and laid it to rest, the heroes now stand at the edge of the greatest cliff in all the world. The land they see is know theirs, but what does it hold?
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?
