Closure
Change the World
One feature of the setting has changed as a consequence of the Fellowship’s in/direct actions and you get to tell the World about it! This could be anything, from the life of a single person to the fate of a nation, to a shift in the very fabric of reality. Your story is not over yet.
Seize Your Destiny
Your PC becomes a powerful and influential NPC. You get to briefly narrate what this means and how it happens. In any case, they are still in play and the World can make use of them just like any other NPC, but they need your explicit consent if they want to substantially change or harm them.
Enter the Legend
Your PC becomes a mysterious and legendary NPC. You get to briefly narrate what this means and how it happens. In any case, they are no longer in play and the World is forbidden from using them as NPCs or from substantially changing the narrative around their legend unless they have your explicit consent.
Pass On The Torch
Your PC exits the stage in a relatively quiet way, becoming an NPC. But someone new steps forward as their heir! Create a fresh new Protagonist with one Growth option already marked to represent the teachings/inheritance left them by your old PC. Like in Seize Your Destiny you get to describe how this happens, and your old character is in play as an NPC for the World to use, but they need your consent to change or harm them substantially.
