In France, 1431 AD, Jeanne D'Arc was burned at the stake for accusations of being a witch. Accusations she did not refute, nor did she try to escape. That is the proper outcome of history.
But now things have changed.
Gilles de Rais was not satisfied with this outcome. Using the Holy Grail, a gift from a benefactor he would not know, Gilles de Rais attempted to resurrect Jeanne but was unable to. Far from disheartened, he instead created a new Jeanne out of the Grail itself, twisted by Gilles's wishes and feelings.
Now their actions have created a road block in history, and thus, the Chaldean crew has a new event to handle.
