How does magica work ?

So is Arcamina from Meracydia? As far as I know, it's the only continent that we know of that fits the bill.

Hard to say, since we know NIN, CNJ, PGL, THM, PGL and other class/ jobs are mobs in Allagan Dungeons like Fractal Continuum/ Research Facility. The fact that their called by their class names and implies that they're atleast as old as the Allagan Empire.

Since the Summoning was specifically invented by the Allagans I am more inclined to think that Aramina is what summoning eventually became due to people actively hunting and killing summoners after Allag's fall.

From what I remember Lalafells originally lived on islands within the Southern Seas and Mhachi apparently had an aliance with them against Nym
