The Tsaesci have actually invaded Tamriel three times, the most notable was during the rise of Reman Cyrodiil. They were defeated by Reman and pledged themselves to the empire as the blades. Versidue Shaie was actually potentate when Reman III was assassinated and became ruler of the empire of Cyrodiil for 300 years.

The extent the Tsaesci, known as vampire snake men, actually resemble something akin to a naga is unknown because of actual first hand accounts are limited and there is a lot of conflicting information.

Back on point I do not think Hadvar was alluding to anything outside of the game Skyrim. Hadvar had just experienced his first encounter with a dragon, a creature supposedly extinct, and then giant spiders. I think the comment ends there with just being a sign of exasperation.
