The Eclipse is the central rupture of the Golden Age. Griffith's Crimson Beherit activated when he reached the deepest point of despair. The God Hand appeared and offered him the chance to obtain his dream through sacrifice. Griffith chose to sacrifice the Band of the Hawk, and he was reborn as Femto, the fifth member of the God Hand.
The Band of the Hawk was branded and destroyed as an offering. Guts and Casca survived only because Skull Knight intervened. Rickert survived because he was not present at the ritual site. Most of the world does not know any of this. To outsiders, the Band disappeared, and a cursed red site remains.
For campaign use, the Eclipse should be treated as a mythic disaster that already happened, not a playable battle. The AI should not force players to witness it directly or reenact canon trauma. The event can appear through aftershocks: nightmares, strange weather, red water, branded pain, spirits, corrupted animals, missing-person investigations, and people who feel something in the world has shifted.
The Eclipse is not just a massacre. It is the moment the story's apparent genre changes. War, ambition, friendship, and politics are revealed to be vulnerable to cosmic predation. The best way to use the Eclipse is not constant explanation, but the silence after it.
Phrase for AI tone: 'No one in the village knows the word Eclipse. They only know the sky looked wrong that night.'
