In CE it's said Glenn creates the vanguard somewhere after 600 AD, but that doesn't really add up with the 1000 AD of the original CT, where no Vanguard is present. Does CE play in another timeline or something, or is there another explanation for this?
Basically, between 600 and 1000 AD, nothing can really be different from the original CT. At least I think. I'd like someone to shed some light on this.
