Upon discovering the reason behind the cave, Leonard and Joan quickly began digging. However, during the excavation process, Joan stopped. "I think this cave might not be the location for the treasure."
"Isn't it a treasure location?" Leonard took a stone from Joan's hand and looked at it carefully, only to find out it was a peacock stone.
Peacock Stones are indicative of copper deposits, meaning that places where these stones are found typically have copper mines. Considering that Sweden is rich in copper, these mining caves are likely the result of unauthorized excavations.
Before the Age of Exploration, the whole of Europe was in a dangerous state of currency deflation. As a result, many Europeans had to resort to bartering.
Even for the majority of lords, there was always a shortage of money. The taxes collected from their subjects were primarily various commodities, not currency.
