From publisher blurb:
It has been a rough few months, but now that the goblin assault on Feldhold has been turned back and the plots of the Black Prince exposed, you four adventurers are able to take a bit of time off. The realm is on the mend and the King is out of bed, sitting in court once more. Times are good, and even more impressive is the Princess and her love for you. Who would have thought a few months back that you and your friends would be hailed as heroes of the realm, and one of you would be seeking the hand of the Princess for marriage?
This adventure book is the first in a series of linked adventures that will take your four characters all the way from 1st level to the heights of their professions. The first of these linked adventures started within the core adventure book, A Life of Adventure, and it was there that your characters played through the story adventure, “Goblin's Wrath”. This first book in this new series takes place directly after the events in the Goblin's Wrath adventure tree, leading to one of your characters seeking the Princess Jenn Free's hand in marriage.
You should have completed the Goblin's Wrath adventure tree in A Life of Adventure and also gained access to the Marriage Track to continue with this adventure book.
If you have not, either go back and play out that adventure tree with your characters, or just assume you accomplished these goals.
