A merchant who freely travels between the Overworld and the Underworld. He acts like he is everyone's friend, is enthusiastically humorous, and is good at bantering. A silver tongued salesman. Where there is profit to be made, you can be sure Sampo is nearby. The information that only Sampo possesses makes it hard not to approach him for help, but becoming his "customer" is not necessarily a good thing. After all, "customers" can quickly turn into "commodities" for the right price.
