The Moaning Lands of the Dead and Dying. Many foul creatures of undeath roam here and seek living flesh, no one is quite sure what happened to this large desert island. Maybe you could unlock the mystery and free the tormented.
A mystic ruin that is well guarded by the family of Dro’Hizzir a great upper class of Shadow Warriors. This is unknown to everyone except for Dro’Hizzir. Knowledge that is only passed down from his forefathers and ancestors alike. Well underground in the city of Pulca. The entrance is found in Dro’Hizzir’s office in his ancestorial vault (that has riches in it as well). In the back of his vault is a narrow tunnel way big enough to fit a normal man in that leads to a ruin of his dead Ancestors and riches of the deceased.
When running a new party, get around the question of plot density by having the first discovery to be a deck of fate, or whatever you call it. If you use a real deck, you should definitely stack it to have the desired outcome, which is to curse the party to attract weird things to happen and involve them. This should not be told to the players at the time, so that they won't just up and try to get themselves 'decursed'. Though quite why they would want to is beyond me.
