Who is Alvin Miller from Red Prophet and what is their importance?

Alvin Miller grew up on Wobbish Road in Vigor Church, North America, as the seventh son of a seventh son and the thirteenth child. As such, he is a boy with special gifts that more often than not decide his future. He begins by using his special gifts haphazardly. He is young, and doesn't realize the strength and power of these gifts he has, or the weight of responsibility that accompanies them.
