Once the War's Over was used to an incredible end in the current season of Friends at the Table.
My google-fu can't find anything. Is Once the War's Over a TTRPG? If so, who is the author? Is it just something Friends at the Table did for an arc? If so, what episodes? I am interested in the concept!
It's the second move in the image! And it features prominently in Friends at the Table's currently ongoing season, Palisade. Most relevant in eps 22-24.
If you're not caught up on n FatT you should also check out the "Number of the Beast" move, it's very funny and in a similar vein.
