Ticket to the eternal void
Nobody knows how you get hold of one, yet there it is. It's thought to be like Death but without the pain, which is instead replaced by eternal suffering in an empty colourless void. If a hero gets one, their god should make sure they don't use it. Some say that hell is another name for the eternal void. Others say that hell is a nice place to sit down and have a picnic compared to the eternal void. The only thing anyone truly knows is that the eternal void is an immutable coffee stain on the tablecloth of reality.
