Just what the topic title asks. Would there be a possibility of Ayleid ruins in Valenwood? I know the Ayleids after the fall of their empire pushed south in Valenwood. I just want to know if they built anymore cities while they were down there. This is all for a RP I'm doing concerning the Ten Ancestors.

It's certainly possible, I suppose, especially considering the relatively amicable relationships some Ayleid kings had with the First Empire prior to Marukh's witchhunt.

Personally, I don't believe there would be many. The Camoran Dynasty controlled Valenwood contemporary to Ayleid rule in Cyrodiil and acted as something of a buffer state between the Ayleidoon and the Altmer. While we know many Ayleids fled there following Alessia's rebellion, with all the lore about "Wild Elves" it appears they opted to blend into the existing population rather than build ruins.

TES:O thinks so, however, and Ayleid ruins will appear there in the game, for what its worth.
