lol indeed
My theory kind of hangs on the idea that Alessia was the first, as she was the first of the Cyrodiilic emperors who made the pack with Akatosh. Reman was then born of Cyrodiil, which is Alessia. And Tiber was, of course, named Dragonborn and survived the Thu'um that had blasted all others into ash, and was pretty much destined and all that jazz. Add in my speculation about the three humans behind the Dovahkiin, and yeah, that's pretty much it.
There were Dragonborn before Alessia.
We're talking Old Cyrod, now. The First Empire of Man, back when Ysmir was seven kings, or some [censored].
Actually, I think Reman qualifies as the first Cyrodilic Dragonborn, and Alessia was mother.
