Anger is a great business, people will share it with you for free and if you're savvy enough, you can sell it back to them. The Rage Mages descended from Belligerus's early followers have found that modern world has just as much use for anger and magic as the ancient world.
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.
