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.
A man was killed somehow and brought back to life. He, uniquely, remembers everything about Death, from the skeleton on the horse that guided him, to the afterlife itself. And the annoying bit where he was wrenched from his jacuzzi. He now has penned the instant best seller, entitled 'To Death and Back: My adventurers beyond the grave.' OR IS IT? Is this man telling the truth, or simply a very good liar? Is it all a fraud?
