This is it. The final confrontation between the protagonist and the Big Bag
is at hand, and things are not looking good for the protagonist. Perhaps he's pinned down, he's locked swords and can't hold on, or he's speeding down the trench with The Dragon
on his tail. In any case, this is the crucial moment where the Hero's strength is about to fail.
All of a sudden, however, the Hero gets some unexpected help. For whatever reason, be it an Evil Weapon
releasing the souls of those it claimed, the intense magical power of killed mentors, or the battle awakening some ancient magic, or a simple hallucination, the spirits of the hero's slain mentors and friends appear and provide some much needed assistance to the hero at a crucial moment. This can range from simple moral support to killing the Big Bad
themselves. Either way, as soon as the Hero's mission is accomplished or his enemies are killed, they disappear, never to be seen again.
