From publisher blurb:
The Avalonian counties of Carnffrid and Dinasglyn are joining through a wedding. The Earl of Carnffrid and the daughter of the Earl of Dinasglyn are childhood friends and, after the expulsion of the Montaigne, this is good news for the folk there, but a third player is going to proof how the love, spite and revenge of a triangle can complicate the happiest moments.
As written, this is a 3-Step adventure set in Avalon and Heroes should be of good reputation and not Montaigne - or at least be able to disimulate their accent. It can be adapted to be played elsewhere or even somewhere disreputable, but background story and motivation should need changes as well.
Only the 7th Sea Players Guide is needed to play the adventure.
