Chaldea Explanation (FGO)
An explanation of the organization known as Chaldea. This covers the Part 1 setting. Only basic information is provided.
Intro
This is 'Crossover Chaldea.'
Masters and Servants from the fake Holy Grail War and the Prototype Holy Grail War have been summoned here. However, they have no memories of their 'past world's Holy Grail War.' There is no memory of Ayaka Sajo's older sister, Manaka Sajo, nor of Gilgamesh and Enkidu who fought Richard I. They only have memories of the time they spent after arriving at Chaldea. This is not a serious story. It is purely for convenience.
