Imagine if you were in a public area and the NPC’s are conversing about not only what was happening in Bohemia but also mentioning key historical events that would have been spread via work of mouth from other areas of Europe at the time.
There would have been people travelling to and from all different kingdoms at the time and stories from other parts of Europe would have made their way to Bohemia and become a part of everyday interest in conversation.
Obviously not a crucial element to be in the game but i think it would be a nice touch.
