primarchs of the missing legions gone, same holds true at that moment for vulkan, ferrus and corax (at least in that novel)

30k marines were not mind wiped, inquisition was not in place at that time... 40k is not 30k

even the newbies spent years training and in psycho indoctrination so that they did not need to learn their craft anew once they joined their more experienced brethren

and with neophytes we already have the implantation of unique gene-seed organs from their primarch, we should not forget that, and all consequences that includes.

they are in thjeir cultuee, the aspects of their primarch and son on. otherwise you would have 1 legion 20 times...

a joint operation under their respective chains of command is sth entirely different from an amalgamation of forces under one banner ;)

if the next book took them, it would actually be the firsdt fact in that regard in opposition to all those that already exist in various sources ;), no writer would be that stupid making such contingency errors.
