pawsplay said:Your logic eludes me. Simply because elves and humans can mix does not mean any other combination is viable, not even human-dwarf and definitely not dwarf-dragonborn. I do not perceive this dumbness of which you speak.
I agree with you completely. Just because elves and humans can mate true, there is no reason to think any other race can. Human-elf pairings have been in fantasy for a long time, so they aren't going anywhere; they are too far ingrained in way too many stories (though, the could have just said half-elves show traits of one race over the other, so pick which one your character displayes).
As I understand it, Tieflings were once human as well in the distant past but were tainted in some way, corrupted by devils I think? Could be that teiflings can have children with humans (and elves and possibly other races as well), but that any child born from such a union careies the same blood-taint, and is therefore always a tiefling.
The curious part question is, why would elves breed true with humans but not with eladrins, with whom they share a common ancestry? Perhaps Eladrin blood is equally as strong as the teifling's - the children of elves (and humans perhaps) that breed with eladrin have too much of a fey nature within them to exhibit anything but eladrin traits. The nature of the feywild wins out over all else.
Maybe several races would breed true with each other, but only the human-elf pairing makes for a seperate and distictively difference race.
