What are the realistic chances, even with a metal detector, to actually find something like that IRL without prior knowledge?
Just seems kinda far fetched to find buried crazy people treasure randomly.
But I could see a starting trait, something like "There were always rumors that the townsfolk here buried the city’s supply of gold years ago. Now that no one can stop you from digging all around town… yadda yadda"
With some kind of vague indicator on the general area of the treasure. But then you only know one and that doesn’t seem like it would help much. Being gold and all.
*Edit: Changed cities to city’s. City, that’s a made up word.
