With the upcoming work on the Army Arc, I feel this would be a good place to throw this out there: war stories
Specifically, something I imagined concerning
Core 45:
"Civilizations (for example, goblins or expansionist humans) should be able to declare war on each other and raise armies. They can send messengers to outlying towns or gather soldiers as they march from town to town toward their destinations"
When these "collective" armies eventually achieve their goal (or are defeated), they should disband, and the surviving warriors should return to their separate homes (perhaps this calls for a party?). These "war heroes" would undoubtedly have stories to tell, and these stories should influence items in the village they came from: engravings, statues, etc.
Also, if an army was large enough (hundreds or more), the personal histories (Legends, Adventure mode conversation) of these War Heroes should reflect what they were present for. For example:
"Urist McWarrior was present at the Conflict of Knives as a soldier of the Scalon Army," makes sense, however, perhaps even historical events at these battles that were within the sight of the warrior could be mentioned, such as
"Urist McWarrior witnessed the death of Goldbrand the Gallant, leader of the Scalon Army," or
"Urist McWarrior was present when Schulpher the Fiend, soldier of the Divine Army, defeated Goldbrand the Gallant, leader of the Scalon Army."War stories, "I remember it as if it were yesterday..."
