Following several alien incursions at the school such as the Daleks (TV: Remembrance of the Daleks) and a Skovox Blitzer (TV: The Caretaker), the tear opened up in around October 2016. The first aliens to enter through to Earth were a pair of Leaf Dragons, and one of them became imprinted onto the skin of Coach Dawson (TV: The Coach with the Dragon Tattoo)
