Ancient battlefield structure

The structure that I am suggesting is a battlefield from an ancient time before the player with various lore implications. This could be some sort of ruined village, field, or some sort of outpost meant to defend from an invasion. The structure could contain armor and weapons such as swords, shields bows, crossbows, and axes, while including other unique loot items such as new armor trims and other things only found here. It could have barricades, barracks, and maybe towers where defenders could have spotted enemies and warned their comrades. It could also include some hidden underground bunkers and tunnels with supplies for survival, however some tunnels have collapsed creating a maze. At the end of this maze could be rare loot like diamonds or ancient debris. Thank you for considering this idea/recommendation, this of course leaves plenty of room to work with and develop other aspects of the game making it, in my opinion, a great idea to consider. Thanks!
