History
Following several alien incursions at the school such as the Cold, (PROSE: Time and Relative) 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) The next to enter were the Shadow Kin and Corakinus, who used the tear to hunt down and kill Charlie Smith and Miss Quill, the last Rhodian and Quill respectively. This incursion was stopped by the Twelfth Doctor, who left the school in the safe hands of a group of students. (TV: For Tonight We Might Die) In late October 2016, a vine-like creature known as the Lankin entered the tear and attempted to feed off Tanya Adeola but it was forced back through the tear by the rest of the group. (TV: Nightvisiting) In November 2016 a single carnivorous "killer petal" entered the tear, and within a couple of days it had multiplied into millions other petals and were slowly starting to consume humans. Charlie was nearly forced to activate the Cabinet of Souls to defeat the petals, but they were destroyed by the returning Shadow Kin now under the control of April MacLean.
