Locals around the village are finding more and more strange and half buried artifacts in the surrounding rocky hills. Old armour, tablets, idols and so forth. The news is spreading and has reached our players ears. Maybe there is an old tomb/s which has been just revealed by the erosion of time, sand and wind?
Maybe the news of this has spread to tomb robbers and thieves, and they move secretly into the area, searching the mountains to find the tomb first. Maybe the tomb robbers set up traps to scare off other thieves?
Maybe the players want the possible treasure inside the tomb also?
Maybe there is an old spirit which is left haunting the tomb, defending its last resting place? Will the players be thieves, or will they be the spirits saviours?
