New Currency for Kingdoms

A common demand is to be able to sell items, but this could harm the game's economy. But what if instead of receiving a fraction of what we spend on the item, we could sell items exclusively in the Hoarder and receive a currency to use and open a safe in the Inn where we can leave combat items and trinkets for itinerant heroes to equip? Furthermore, it could be used for a new version of the DD1 mechanic of "putting out the torch" by running a torch protector that does not let you lose light, but makes you run with it as if it were 0 (or 5-10) until it is removed.

There could be a Tree in each Inn similar to the Militia Tree in which there is no specialization, which deals with what you can do with this new resource.

It could even be useful for Confessions Mode to bet on whether the relationship will be positive and if it will repeat the same affected skills once and to reroll the modifier and objective of a region once per Inn.
