Like DMOE referred to in my post on this: "mixed race couples are having increasing trouble conceiving children". That's means what it says.
So...
so that means that six childrens of Rain(half elf) and Sonya (human) and of rain pre-dragon called (brian) are all sterile
Yes, they are.
It was stated, back in the What Is A Half-Elf thread, that if you breed a half-elf with a human, then breed that with a human, eventually you'll get something that is, for all intents and purposes, human.
However, would this For-All-Intents-And-Purposes human be considered human enough by Aeridin to make human babies with another human?
This is a rather hypothetical question I guess. I suppose you want a figure here, like after 8 generations or after 6? If I give that then I can already see the bios appearing with genealogical lines and "X generations back there was an elf in my family, so this char has pointy ears."

I'll give you a number, 6 generations. However, we reserve the right to change this.
On Tieflings and Aasimar, they cannot have offspring. Yes that marks the end of these races.
Is the result of a birth between a hypothetical Elf and Drow Sterile?
No it is not, it's still an elf, as both parents were elves. Just like strongheart halflings and ghostwise halflings can have children, or gold and shield dwarves (they're dwarves) or forest gnomes and regular gnomes(they're gnomes).
