Adventurers from across the land seek the infamous mystic jewel crafter.
The tinkerer is known for producing magically imbued trinkets which aid
the adventurers in their journeys. But as a cost for the services, the
adventurer must sign a contract to bring back a rare or unique
treasure/artifact, which the tinkerer is strangely specific about it and
its location. The tinkerer is always traveling and is accompanied by a
pack mule pulling a cart full of goods and wonders.
