Crack theory:
What if... Saint Germain transported Richter into the future to battle away Soma Cruz as Dracula's reincarnation? After all, in the Sorrow games, Julius is too old for the job and got his butt handed to him by the flame guy in Dawn of Sorrow (which kinda of pissed me off). Julius doesn't seem to have any descendants, otherwise they would have shown up as the Belmont in duty for the time. The whip stayed behind so it could fall into Julius' hands by 1999 and was left guarded by the Morris family.
Problem with the theory is, now that we are missing a Belmont, how did they, you know, procreated? We could say that Anette was left with a baby, and since Richter was not around to train him the whip was forced to switch hands, and that solves the issue. The Belmonts would have to retrain themselves to use the whip again, which would somewhat contradict Eric Lecarde's words in Portrait of Ruin, saying the Belmonts can't touch the whip until 1999. However, could it be that the Belmonts had to ready themselves for this date?
