After Hill returned to the Magic Tower, he read all the newly acquired books, focusing particularly on the legends of the Goddess of Gold Coins.
Although this Goddess of Gold Coins does not even have her own country and claims to never contest for worshippers with gods from other countries, she only has a city of commerce as the location of her Main Temple. Yet, she remains one of the few deities that have existed since ancient times!
The reason why human kings in this world have little notion of coin minting rights is largely because humans seem to have used the transaction method bestowed by the Goddess of Gold Coins since their appearance.
The people of this world might be kept in the dark, but the outsider, Hill, was well aware that each transaction with these currencies greatly benefited the Goddess of Gold Coins.
She is named after gold coins, but in reality, she primarily presides over divinities related to trade and commerce.
