Ausonia: Masters of Shadow

From BoardGameGeek:

In Masters of Shadows the base game is extended with Leader Cards, new Favour Cards and Mission Cards to seize powerful Artefacts. Leader Cards: If you are done playing with everyday nobility, slip into the roles of 6 leaders from great houses, which have special abilities and very distinct gameplay style. Leader Starter Decks: These leaders not only have unique abilities, but also 3-3 respective Favour Cards. The Gem Cards of the base games' starter decks just have to be shuffled with them and they are ready to play. Artefact Cards: Those longing for power have the opportunity to acquire the invaluable Artefacts of 6 guilds, providing further advantages during the game. Mission Cards: These Artifacts don't come easy, missions have to be accomplished to gather them! 9 House Leader Cards 27 Leader Starter Cards 40 Artefact Cards 10 Mission Cards 1 Rulebook
