Possession might be reasonable cause for execution, but I can see it being coated on the treasure in a Chieftan's burial chamber, or what not. Does repeated contact make the poison work faster? Go to Comment
That night the PC's dreams are rife with turmoil, dreams of death and fire.
"Burn the witch!" The mob screams, pulsing from within with a hatred rarely seen in the world. No longer composed of individuals, but as one organism devoted entirely to hatred the bound her and beat her, tossing her back into the small boat she'd been trying to hide in. Filling it up to the gunnels with tinder and wood they kicked it out into the current, tossing torches onto it as they did.
Upon waking the PC notices that the locket, which was once in their pocket, is in their hand and seemingly coated in tears. The character, if motivated to try and part with it, will find themselves unable to, having become in the short time they've owned it, emotionally attached. They might have a few nights good honest sleep after this, but eventually the dreams will resume.
A faceless man, with a dark hood drawn over his head, is crying over a stream, though you can't see his face. The willows around him seem to be in mourning as well, even more than a willow is normally, the tree seems to slouch with a feeling of defeat. The man, still crying, rises out of the crouch he was in and hold out a necklace with some sort of silver pendant on the end, and then tosses it into the water whispering to something unseen, "For you, my darling, I'll never forget."
The PCs eventually make it to a town, to restock and the like, but as they're walking in they pass by a grisled old man, shackled to the wall. He seems to be within steps of Death's Gate, but as the PCs walk by he looks up, and locking his eyes upon the locket that the PC had unconciously put on, he started.
"Child, where did you get that? The trinket you wear round your neck, and the tears it carries in its heart?"
Seeing his sudden movement the guard starts, and suddenly his crossbow is pointed at the PCs, and the trigger is all but pulled.
"Calm yerself, Crombie. Just cause I killed you dear old man, and burnt his damn house to the ground for what he did to Ansonia when we was both kids, doesn't mean everything I do around you is out for your death."
As the PCs and the chained man, who eventually names himself as Abner, talk about the locket the story comes out about how it was his girl, his lovely Ansonia was burnt to death by the locals for fear that she was a murderer, demon-worshiper, and necromancer. Fueled by his hatred Abner proceeded on a campaign against the locals, killing and raiding, and was only recently caught by a group of adventurers. All he asks for from the PCs is that they give him the locket. Go to Comment
The young man was part of a bandit clan, but after getting caught trying to steal from the clan's leader his punishment was brutal and quick, though his death lingered. If the PC's are chasing this clan for some McGuffin or another, the fact that the boy is a week dead should be enough, but if they summon his spirit for information, it will tell them of its death and urge them to avenge it.

"As you make your way out of the forest, and the town on your map comes into view, you see the walls are painted in bright, sickly shades of red, green, and blue. The houses crouched outside the walls are clearly abandoned, and the city gate seems to have been battered down." Go to Comment
"As you walk through the seedier part of town, trying your best to ignore the piles of refuse you step over, you see a man on the side of the street. He's leaning against the way watching you, and as you look closer, you see that he has a knife sticking part-way out of the side of his head." Go to Comment
