* Shirou body it's a "oc" Shirou that never was rescued by kiritsugu, he was devoured by the grail mud.

* Shirou main soul is from UBW last bad ending.

* Shirou has a total of 4 souls, Fate last bad ending(Devoured by mud), UBW last bad ending(pulled by Gilgamesh chains), Heaven's feel sparks liner high and normal ending(where he dies using Excalibur).

*Shirou has memories from the other bad endings, but not much of that soul is left to matter(no extra circuits). He has memories from prisma illya and peeked at other grail wars.

*Shirou arrived on year 602, arrived 1 year before the Siege of Antioch(the first use of the proto-Astartes of the first legion)

*Curiosity: On warhammer timeline, the first legion was deployed before the year perturabo claims to be born, and all primarchs are born at the same time, so, the legion was made before the primarch, probably with DNA collected from the embryo or fetus.
