In a world where emotions are harvested as physical artifacts, you play as Cassian, a heart collector who must navigate the treacherous districts of Aeterna, a city where the souls of the heartless roam free. Each heart you collect is tied to its owner's memories and emotions, creating an ever-shifting maze of alliances and betrayals. As you gather hearts, you must make choices that affect the city's fate and the lives of its citizens, ultimately deciding if you want to restore these hearts and bring love back or use their power for your gain. With each heart comes a different narrative path, leading to multiple endings, and each choice will echo in the emotional landscape of Aeterna.
