Sorry it’s a bit late, but I was having trouble finding references, so I’ll just explain.
Basically… anyone’s secret stash of stuff! Is it a hidden hobby? Something gross? Something embarrassing? Is it a dragon’s hidden hoard? Anything for any reason as long as it’s a hidden item / items!
Have they been found out? Are they adding stuff? Guess we’ll see!
You’ve got 30 minutes to create followed by 15 minutes to submit! Have fun~
