Jaune has been expelled(shocking I know). With the exceptions of teachers like Oobleck and Port everyone turned their backs on him.
Now he lives in a huge house in Mistral alone(he is in good terms with his family)
Meanwhile Ozpin and Salem both decide to tip the battle in their favor. Using a spell they try each to summon the 7 servants(maybe the other classes aswell).
Here goes in two ways. The succede with each group getting full sets of servants. Yet someone up high didn't like this and decides to have some else get servants aswell(jaune).
The other they failed and Jaune ends getting the 7 servants.
Jaune servants:
Saber-Artoria
Castet-Tamamo
Rider-Medusa
Berserker-Morgan
Archer-Atalanta
Lancer-Scáthach
Assasin-?????
Assasin is hard either serenity ir be the only male in King Hassan
