Those damned racers are so pesky it made
me wanna leave. It's no wonder the dragons took off.
HEY! Maybe that's what the deal is. Perhaps the Nereverine leaving had to do with the racers being annoying. By the time the rumor got to Cyrodiil, people are thinking that St. Juib drove the cliff racers out, when actually the cliff racers drove the nereverine to Akavir. Just like the dragons.
j/k (in case no one figured that out)
