This is a mod for Mount & Blade II: Bannerlord that changes the appearance of the game's banners, from the classic boring stuff to something more detailed and interesting. What does it do?

With this mod, the clan's cultures inspire the banners. You will also love that they will become more detailed. Hence, the appearance becomes more lore-friendly. It changes all clans, minor factions, and kingdoms banners seen in the photos. 

This is very simple and easy to install, but you will also have to download and install the latest version of the Banner Color Persistence mod so that the banner colors will also affect the clothing of clan troops.
