I have some concepts I made a while back that are Cyrodiil related, thought I should post them here if they could be any use. Feel free to use them if they work/fit your vision.

In Oblivion, the symbol to represent Anvil was a heraldic depiction of ermine. So, I thought it would make sense if Colovia, particularly the Gold Coast, had some stoats to hunt as a source of this fur pattern. Made for a potential Furrier's Guild Oblivion mod.

This one comes from a headcanon of mine, that the Topal Isles are used for Nibenese industry, particularly plantations and estates owned by Leyawiin and Cyrodiil City fruit and palm-wine companies. The look for these workers come from similar real-world depictions of palm-wine collectors, with a Nibenese touch.
