Descent had quite a lot of expansions come out for it before it changed to the 2nd edition. Making sure that people get to play with all those cool figures if they like the new edition has been a priority for Fantasy Flight Games. Having said that, I'm letting you know that they've released the Stewards of the Secret Hero and Monster pack.
The set comes with four heroes and ten monsters. As is customary for Fantasy Flight releases like this, it's a lot more than just some new figures. There's also two brand-new quests that you can go on (using those new heroes or not). It's up to you to keep the works of the mad sorcerer Devis out of the hand of the evil beings looking to get it, lest all of Terrinoth be in deep, deep trouble.
