Here is the current progress build. The random banner/flag/crest generator is in, and each culture now has a flag which is displayed when a settlement or fortress is selected. I will be adding more variations and improving the graphics in the future, and exposing this to be moddable. The symbols on the flags are influenced by cultural traits, so a primitive war-like nation is more likely to have an axe than a fish on their flag, while a realm of insane apes might have a tentacle as their sigil.
The work on the character system is still on-going and should be visible in the UI soon ™.
