Reading the Pocket Guide first edition, the section on Skyrim.
When it explains Ysgramor returning to Skyrim to drive the elves out it then states that this may conflate the early reign of Nordic kings. does this mean that Ygramor didn't personally push them all out but he was the one to start it? Just a case of his legendary status overshadowing other events?
Ysgramor and his 500 companions started the push to drive the elves from Skyrim, and were wildly successful. However, Skyrim wasn't free of elves until the thirteenth of his family line, King Harald, completed the job his great great great great great great great great great great grandfather had begun. So the conquest in actuality took generations. Have you read The Five Hundred Mighty Companions? Not that it tells a whole lot. The Songs of the Return will help you there.
Also, as I'm not that far into Skyrim yet, how did the Falmer remain within Skyrim if it says all the elves were driven out. Did they remain in hiding the whole time, hiding within the caverns?
Pretty much. At least, as far as I know. Evidently there's a book in Skyrim that I haven't come across yet that talks about how the Falmer came to be as they are today.
Edit: Also does the conquest of Tamriel begin with King Harald or did this begin before.
I believe that the founder of the Nordic Empire was King Vrage "the Gifted", as he is the first to expand the High Kings rule beyond what is normally considered Skyrim. But since there was no precedent of there being a Skyrim before the arrival of the Nords, and given that they were undergoing a constant state of expansion, you might as well say that Ysgramor started the conquests of Tamriel.
Edit 2: I will continue to use this thread to ask questions on the Skyrim section of the Pocket Guide. Hopefully all of my questions don't already have answers somewhere else >.>
1.King Vrage the Gifted is mentioned as being the one to start expansion and who created the first Nordic Empire and King Borgas is the last King as part of the Ysgramor lineage. Do we know how many there were between Vrage and Borgas?
2. If the Moot's job is to appoint the next High King how does the Ysgramor line stay intact ad upon the thrown?
To answer each question in turn:
1: One. Hjalmer. http://www.imperial-library.info/content/first-era
2. "The Wild Hunt (a bestial horde of monstrously transformed Bosmer) kills King Borgas of Winterhold, the ruler of Skyrim and last of Ysgramor's line. The Moot - a council with the
duty of choosing the next king from qualified members of the royal family - fails to appoint the obvious and capable Jarl Hanse of Winterhold, which starts the disastrous War of Succession." - http://www.imperial-library.info/content/first-era
The Ysgramor line stays intact because the only candidates on the ballot are his descendants.
