About Honor's End, from BoardGameGeek:

Honor's End is a 1–4 player cooperative deckbuilding adventure set in a medieval world overshadowed by a mysterious truth. You can play it as a standalone session or as part of an episodic campaign that gradually unlocks new content and challenges. Players must band together to overcome escalating threats. By wielding hero, action, and equipment cards, they'll strike at their foes while fending off dishonor-brought on by danger dice rolled each round by their enemies. Each knight chooses a path of Valor, Fortitude, or Wisdom, building a deck that shapes their abilities and tactics. Enemies, forged from the traits of Wrath, Deceit, and Despair, create unpredictable and unique battles every time you play. Victory demands more than raw power. Success lies in balancing honor, clever deckbuilding, and shrewd use of the Temple and Monarch reward tracks. Defeat all three enemy champions to claim victory-or watch your honor slip away. -description from the publisher
