i never thought of any of the Wygol villagers as true Belmonts (as in they would have the Belmont last name), just descendants of them. but i suppose some of them might have been.
and yeah, based on the audio drama, Richter didn't put down his whip after what he had done in sotn. so i was thinkin perhaps what they really weren't allowed to do was fight Dracula again until he was at his maximum power. and the best way to avoid the temptation to do that would be to not touch the whip until then as prescribed by the prophesy. perhaps after Alucard sealed Dracula, no one thought Dracula would be back anytime soon, so Richter kept the whip and Magnus decided it wad time to look towards Alucard as the new lord of darkness. but yeah of course, just speculation.
