What if Aizen found himself on the verge of being defeated during the Winter War and changed the actuality of events? Meaning, erased everyone's memories to make them forget all about Soul Society and with his power of illusion (strengthened by the Hogyoku) gave them fake memories to make them think they've been living entirely different lives?
Okay, well here is how the characters will go, I have seperated them in "connections" categories, meaning that the people in those groups interact with each other in their everyday lives the most, though eventually they all end up interacting with one another.
