We had this issue in our last game session..
The ending a hero rises states that, when a player reach the CoC with 13 or more fate he WINS the game.
Are a player then allowed to reach the CoC without any fate. And what would happen.
We had a player reaching the CoC through the treasure chambers teleport. He had no fate and would therefore not win the game, but was able to use the cheat fate spell in the next players turn giving him enough fate to win.
