Ever wanted to add a legendary artifact to your campaign, but you were worried about PC’s getting their hands on it?
Or you put the Legendary item in your game and the PC’s already managed to get it?
What to do, and how to fix it.
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.
