the othe dragonborn were the emporers of cyrodill/tamriel, and were soul bound to the amulet of kings. this may have resulted in thier total absence from modern tamriel, and as the current dragonborn is free of the burden of keeping the dragonfires lit he may endure for eternity like the nerevarine.
