This Dragonborn stuff tickles my fancy.

For my character, I’m using my Nerevarine character from TES III (remember, the Nerevarine was made immortal by the Corprus Cure after his fight with Dagoth Gares at Ilnubi given to him by our favorite Telvanni Wizard Divayth Fyr).

After leading the nomadic ashlanders east, seizing the west Akaviri lands from the Tang-mo and barely missing the catastrophic landfall of the Ministry of Truth. He rules as Khan of khans of the unified Ashlanders for many years but he grows bored and returns west where he treads Skyrim unmercifully underneath his chainmail boots. He seizes the meadhalls from countless chiefs, kills countless thanes; generally killing and plundering on a grand scale. Through misfortune he is captured by Skyrim forces during his forays and starts TES V as a prisoner...yet again.

Nerevar Incarnate and Dragonborn...its gonna be awesome.

Look at your own family tree to see how spread out a bloodline can be. There were over 20 emperors in the Septim bloodline alone, most of which had multiple children who never became Emperor, who had multiple children of their own. And that's just one Dragonborn bloodline. There were many, ranging back for centuries.

The main character of Morrowind was said to be http://www.imperial-library.info/content/morrowind-lost-prophecy:

From seventh sign of eleventh generation,
Neither Hound nor Guar, nor Seed nor Harrow,
But Dragon-born and far-star-marked,
Outlander Incarnate beneath Red Mountain,
Blessed Guest counters seven curses,
Star-blessed hand wields thrice-cursed blade,
To reap the harvest of the unmourned house.

Did anyone else notice that Mankar Camoran was wearing the Amulet of Kings and did anyone else notice his heritage and powerful family? I'm pretty sure the Camoran family would count as Dragonborn, and there are others, as well. The Septims were merely the most famous of the Dragonborn, but I wouldn't be surprised is Alessia was Dragonborn nor would I be surprised if Reman was, as well... among other, lesser known individuals and their relatives.

Damn!!! I forgot about that. Even better.
