The Coffers of Kundarak
House Kundarak, stationed in the Mror Holds, guards the treasures of the continent and beyond. Using the unique magic of their bloodline, along with the dwarvish knack for construction and ingenuity, they know how to keep everything safe from every sort of thief. Most of the time they hide everything away in the central vault located in their mountains.
What would be so valuable as to prompt them to hide it elsewhere? What secret is so precious that they don’t even trust themselves to protect all the keys? More to the point, when someone gives them an item that valuable, how do they get it back when it’s time for the safety deposit box to open?
The better question might be whether you want to be paid for getting it for them, or whether you want the treasure yourself.
