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.
- The Lost Prophecy
Nerevar Incarnate wasn't just born in the Empire. That wasn't the significance the prophecy pointed to. The symbol of the Son of Boethiah was neither Hound nor Guar, but Dovahkiin.
So Dovahkiin is inextricably connected to the unlawful overthrow of authority? Makes sense. If Skyrim is to be believed, then the Dragonborn's entire purpose was to overthrow Alduin and his rule of dragons. And if Alessia is Dragonborn - not really my cup of tea but Skyrim says so - then, well, I think we see a pattern here. Seat of Sundered Kings?
His Critical Harvest's upon us, if Dragon-born's returned. I expect VI to be the last game set in Tamriel, before Many Headed Talos makes way for a mass exodus to Akavir. I think the trajectory is Westward, and we're in the twilight chapter of Tamriel's significance. The Gray Maybe is learned itself. Dawn's Beauty is too old to tell a new story, anymore.
Change is coming. It is written in the firmament. Dovahkiin has lit our star-way across dreamtide, we'll make the journey by Moon and Star.
However, what does this glyph similarity mean? Perhaps it shouldn't be read as the Nerevarine-Last Dovahkiin similarity or common destiny (perhaps those two have something to do with bringing peace in matters turned wrong by gods or godlike beings) but a Boethiah & Last Dovahkiin thing. Boethiah is pelased when blood flows, no matter whose blood it is; whether it is brother killing brother or it is enemies slaying eachother -both is good. Let's point out that the Dragonborn does bring an uncertain peace to Skyrim at last but the pathway to this is very bloody. Are great heroes loved by the Daedric Prince of plots and deceiving?
I argue the Nerevarine became Dovahkiin, when they became Huntsman Bold of a new Wild Hunt - a new destiny - with the Emperor Tosh Raka and all his blood the Hare. Hence the Bloodmoon tide-journey to Akavir, moon of beasts, and Dovahkiin's intimacy with the star-trees. He's harvesting the worthy fallen, to his Sovngarde.

The Dragonborn is usually the one that "ushers in a new age". A rebelion/uprising that later leads to peace.
The key tho is Dovahkiin goes missing. He "fails" so we learn not to. Dovahkiin doesn't stick around for worship and Empire: no, Dragonborn lives in the Heart of the World, not their temples. The elves can't hide the truth Auriel died in the Padomaic's mutiny aboard Direnni. At least the Orsimer are ashamed for their lie, the Direnni have been waiting for godot in stubborn duplicity.
Perhaps that's why Sep and Septim weren't the Last? Because they were worshiped and loved, through power and corruption. We'll see if LDB can resist Herma Mor, or if he gives in to the Woodland Man. Think of the Songs of Wulfharth as the Trials of the Incarnate.
