Monument is a city of ghosts.
For eight days of celebration, the people of Monument honor those ghosts. The spirits speak to the living by possessing machines and computers, and the people put on great shows to entertain those who have moved on.
For those haunted by spirits, those eight days are living hell.
For those that relished their time in this world, there's the unspoken wish that this time could last forever.
I'm running a tabletop RPG campaign set in Monument, and drew a body of work to set the scene and the story.
