Adding to your Saga
After each adventure, the players retell their most heroic moment and that is added to their Saga. It is up to the Game Master to determine Level Advancement, but a player should add a line to their Saga for each level.
The Saga is what you are creating, while the Game Master creates the situation, what the heroes do within that story is what makes them legendary. A Saga could be more than just heroic battles, it could be a fumble so awkward that it is legend that anyone survived. It could be that a silver tongue was more powerful than a sword. Your Saga is what makes this your game.
