From the announcement:
Fantasy Flight Games is pleased to announce The Last Banquet, an epic, large-group game for six to twenty-five players!
In The Last Banquet, each player takes on the role of a member of the Royal Court, from the King himself, to the friendly bard, the alluring witch, or the wise seneschal. Acting out their respective roles, players must use the actions allowed to them to try and accomplish their teams' agendas. However, you’ll need to be judicious in your actions, for the King is watching closely for signs of disloyalty–and not everyone at the banquet table is on your side.
