Spiritfarer

The player takes the role of Stella, accompanied by her pet cat Daffodil, who takes over from the mythological Charon as the new Spiritfarer, a ferrymaster who must sail the sea to find spirits, grant their last wishes, and finally take them to the Everdoor, a gateway to the afterlife. In order to assist with her journey, Charon gifts both Stella and Daffodil with the magical Everlight.
After Charon passes through the Everdoor, Stella procures a ship of her own and begins travelling the world, picking up spirits and helping them fulfill their last wishes while befriending them along the way. As she picks up more spirits and collects resources, Stella expands the ship and its capabilities further. However, Stella must eventually begin sending the spirits to the Everdoor, helping them pass on from this world. Each of them gives an emotional sendoff as they thank Stella for everything she has done for them, leaving her a spirit flower to remember them by.
As Stella sends off more spirits, she begins occasionally encountering Hades, in the form of a giant owl. Hades shows Stella images of what was apparently her past life as a palliative care nurse, taking care of terminally ill patients before falling terminally ill herself. Hades then questions Stella's motivations, wondering whether her desire to help spirits is altruistic or simply a selfish means to ease her insecurities. As Stella sends more spirits to the Everdoor, butterflies begin to gather in increasing numbers on the bridge of her ship, eventually forming a humanoid figure; this is not another spirit, but a personification of the voice of her sister, Lily, talking to Stella while Stella is unconscious in her hospital bed, remembering old memories, good and bad. Stella chases the fragmented conversations she hears from her sister, wanting to hear her, to see her one last time.
Eventually, Stella sends off the last spirit through the Everdoor and she has one final confrontation with Hades. Hades reveals that Stella's body is on the verge of death in the real world, and it is now her time to pass through the Everdoor. With her purpose fulfilled, finally ready to move on herself and accept death, Stella sails back to the Everdoor with Daffodil one last time. As she passes through the Everdoor, Stella hugs Daffodil close to her, and, like the spirits before them, they both become a constellation in the sky.
