The most interesting thing about this series is the tiny blue creature that shows up on the bottom half of the page. If you look carefully in the last panel, you can see it crapping out an urn-full of valuable jewels. That creature is a converter – it eats valuables and craps them out so the bearer can bribe people for information.
