The PCs have been traveling for a long time down the same stretch or round with no sign of anything suspicious. As they cross over to the next hill they see a gigantic splater of blood with a bleached dragons scull in the center of it. It the dragon skull's mouth is a tattered backpack with something wiggling inside of it.
What if when a character died and the price to bring him back into the world was to allow an evil or good version to be placed in the world with the sole purpose of killing the character that just got its life back? The copycat character would die apon completeing his mission.....or would he?
The road has never been more than an overgrown mud track, little travelled and little cared for, petered out to nothing more than a flattened earthen line, barely distinguishable from the rest of the landscape. The soil is dark and fecund and dark oaks stand like sentinels at the forest edge, their branches high and leafy. From them hang grizzly human bones, skulls and shiny precious stones. Who put these strange totems there? Are they warnings? Do the PCs dare to take the stones?
