I just discovered the Labrynthian and it was an amazing moment, the scenery is fantastic and it got me thinking how did it get there?
I thought it was a little sort of village built by the nords during some sort of war because of the massive walls. I could tell people lived there because there were hut everywhere.

What do you thing? Leave ideas

you could also check the imperial library for more info but I believe that UESP is more organized so I stick with that site.

Thanks
