Here'd what info there is thus far:
Triumph and Treachery is an expansion that allows 3 or more players to battle upon the tabletop… and in the end, there can be only one.
Its a hardcover expansion book, that comes with a deck of 36 game cards, 5 player turn cards, a pouch of game victory coins, a book with galleries, new artwork, examples of battles, and the rules for playing Triumph and Treachery with 3-5 players.
The cover of the book is a Dwarf fighting a Chaos Warrior in combat, with a Dark Elf Assassin sneaking in behind.
