There's a piece of parchment right outside Seyda Neen, that mentions a city called Stormwind. I have searched UESP, and of course the closest city in name is Stormhold. I was thinking maybe it's a subtle reference to WoW players coming over to ESO?

"I know you've got a place above that store in Stormwind, but you really have to join me in Vvardenfell. I've been here less than a year and I've already got my own place just outside Balmora. I'm making enough gold that I take voyages down to Vivec City every month or so."
