From seventh sign of eleventh generation,
Neither Hound nor http://www.uesp.net/wiki/Lore:Guar, nor Seed nor Harrow,
But http://www.uesp.net/wiki/Lore:Dragonborn and far-star-marked,
Outlander Incarnate beneath http://www.uesp.net/wiki/Morrowind:Red_Mountain,
Blessed Guest counters seven curses,
Star-blessed hand wields thrice-cursed blade,
To reap the harvest of the unmourned house.

So this means the Nerevarine is Dragonborn, and given a Dunmer's lifespan, it is conceivable that the Nerevarine could also be The Last Dragonborn, two hundred years later in Skyrim.
