A good camping-place with something extra: a gallows with a hangman, reduced mostly to bones and a few rags. It marrily hovers in the wind. Any manipulation will make it fall apart. An excellent camping place, except for the midnight hours, when ghosts of those executed haunt here. Some wail for their crimes, some re-live their execution over and over, some want to have a talk, and still some others want to scare the Living for fun.
The PCs are walking along the road, when suddenly a bunch of bandits attacks. The player's dismiss it has just a random encounter, when they find an ornate ring on the leader, obviously out of place with the seemingly poor bandits, who could only afford cheap leather and weapons. This ring has a symbol on it, which, if researched, sets the PCs on a quest. And from then on, the players don't look at random encounters the same way...
