Can explain what the Yellow Yard is. I know it's The Yard Stick Hussie places between the two 4th walls that John and Jade traveled between but what is its purpose of being between the walls in the first place?
Okay so Hussie is a character in the story and he said that while his self-insert’s appearances would increase his direct involvement with the story would be limited to the space of one yard. That one yard being the Yellow Yard, or the two fourth walls he set up for John and Jade to travel between.
