Most rooms have these; simple secret passageways to other parts of the Inn. They're fun and all, but they don't do much.
"Fortunately, they're not the only kind of Secrets here. After Tier 1, you got Tier 2 Secrets. These ones are harder to find, but if you know what you're looking for, then you start seein' them everywhere. Some Tier 2 Secrets lead to other parts of the Inn that aren't regularly accessible, like the Clock Tower, or some of the Portal rooms.
