Knapsack

In this cooperative game, players battle a nameless Darkness consuming the world by telling each other uplifting Stories. Each player picks a hero class (druid, warrior, etc.) and receives a starting hand of Class, Character, and Study cards as their "knapsack." Over four rounds, Darkness cards are drawn followed by Story cards used to fight against them, which must be completed by players adding Trait, Light, Skill, Activity and Ability cards that match the Story's requirements, while also trying to level up their characters by acquiring skill tokens and Treasure cards.
On the fourth round comes the End Battle, in which all Stories must be finished to defeat the Darkness.
