New historical maps

So basically I think it would be cool if there were more ancient things from the ancient builders and also I know no one from mojang is probably gonna read this but for bedrock whenever I install a mod it will turn achievement’s off but in Java it doesn’t so could you guys please fix that? So anyway back the the buildings so there would be a new kind of villager and it would sell old maps to these old structures once you find these structures there would be a new mob called the ancient builders and they would act kinda like vexes and how they can go through walls some of them would be good and help you find loot while the other would be bad and try and steal your loot or somthing it’s probably a stupid idea but idk I guess you can decide!
