[PF] Planning Dark Sun, need interesting haunts

[Antariuk]

So I am busy planning a Dark Sun game for April '16 and my idea is to sprinkle some haunts (http://paizo.com/pathfinderRPG/prd/gameMasteryGuide/haunts.html) over Athas. For those who don't know this little rules element from the GameMastery Guide, it's bascially a combination of creature mechanics (undead) with trap mechanics to get something that can replicate every haunted house cliché ever, and then some. Very cool if you want a challenge or barrier that can't be destroyed by the depletion of hit points. Does anyone have ideas for desert-themed haunts that go beyond people having died of thirst?

I'd also love to use haunts as a delivery method to grant the PCs some insights into Athas' history, like a ghost telling them something or they must dig up the remains of someone to give them a proper burial and find a piece of information in the process or something like that. However, I am unsure what pieces of information would be "right"... my players have never played Dark Sun so I can use pretty much whatever I want and canon be damned, but what might be interesting enough to not be forgotten about 1 hour later?

Any ideas?

The ruins of Giustenal is haunted by a conglomeration of the spirits of the dead called the Caller in the Dark. Though normally this is a standard enemy, it could be redone as a haunt.

Interesting... didn't think of using Giustenal with haunts, but that would actually be a good fit. However, going from what I've read that's pretty much mid-level stuff and not something I'd want to throw at a beginning party. But I'll keep this idea in mind ;)

Well, the old favourites of Dark Sun are things like soul-devouring cacti, location-bound insane elementals and defiled souls.

Remember that there a loads of insane elementals on Athas as well as the last few screaming nature spirits, so stuff to do with them would be fitting.

I'm not sure that people dying of thirst has the emotional backstory usually seen in a haunted house tale. You usually want spurned lovers, treachery, greed, or incomplete life goals. Perhaps instead of just "we ran out of water" you could have a water source that was poisoned to spite another, and the haunt continues to poison the oasis on anniversary nights until it's dealt with. Maybe you could desert-up the ghost pirate ship with a ghost bandit gang that attacks merchant caravans and takes the goods out of the living world into the lair of their remembered past.
