Chapter 111 - Chapter 109 - Exploring the Underground

Once Milo had realized this fact, the twins seemed to laugh at his reaction. They went on to explain that around 1 year ago, the man who owned the carousel discovered the gate in the storage area they entered from, He chose to reach out to a private gate crashing crew. These private crews were less common nowadays due to the GAA running extensive background checks on gatecrashers and using magic satellites to detect gates. Back when the gate was first discovered, these satellites hadn't been invented yet. Since only the boss remained in the gate, the magical energy signature given off by the Underground was too small for the association to determine it was a gate that needed to be closed.
