In d20pony, It's been a while since the last treasure chest. Will we be seeing one of those in the foreseeable future, or maybe some other wildcard treasure for the upcoming adventure? Like maybe a mystery Cool Thing found in the trade depot, or on the ground, or a secret sidequest reward or something.

Treasure chests are rare — even more so now that the story updates weekly instead of daily —, but there will be opportunities to find more in the future. It wouldn't be exciting to find one if it were a common occurrence!
