Merycidia (SPOILERS)

I wonder if the Dravanians are descended from Meracydian dragons, since it seems like the 5 races migrated there after the 5th or 6th umbral era. Same goes for some of the beast tribe as well.

Also it seems like the inhabitants of Meracydia where the originators of summoning Primals, since it was only after conquering Meracydia was when Allagan SMN came to be

Well, it could be that the Dravanian dragons and Meracydian dragons are cousins to one another. In fact, it seems likely. But saying the Dravanians are the descendants and not the ancestors is a bit of putting the chicken preemptively before the egg.

As to the summoning of primals, you've not quite got the right of it. The war with Meracydia was when the Allagans developed the art of summoning egi as a counter-measure for primals, but that isn't to say that the summoning of primals itself was never practiced before the war or by other cultures than that of the dragons. It was just the first time that it was brought to bear against Allag.
