The PCs enter a dilapidated old town where murders occur without provocation by men nearly gone insane, they meet a mysterious stranger, people on watch fall asleep quickly, and for the love of (Insert deity here) can’t get a decent night’s sleep (That is, they sleep, but don’t really feel rested at all).
A continuation to the plot The Dreamweaver. This time, the PCs might not be so lucky…........
(Recommended avg. Hero lvl: 10-13)The heros find that either a peasant went insane and killed the mayor/king/other high ranking official and says that the “Man in his dreams” made him do it, or, simply the high-ranking official died in his sleep for no apparent reason.
When you sleep, your soul briefly returns to the place where it was created/goes to when it dies, and seeks nourishment. Everybody's soul is created with a little link (or you could say a greater entity calls it back) to that place so that it can return easily, but upon death, the soul returns via that and annihilates the link as if returns.
Also, as an added thingy, you could say the entity supplying the link, or residue of the links themselves, (whichever) is the source of all arcane power.
