Eurotunnel bombing

The Eurotunnel bombing was an incident, involving an explosion in the Eurotunnel between England and France, which occurred five days prior to the attempted coup d'état in England and was a contributing factor towards it.

Background
Due to the manipulations of the Roman Catholic Church, under the control of Fiamma of the Right, the French government caused an explosion in the Eurotunnel which damaged all three tunnels and cut off Britain's sole land route, regardless of the damage it would do to France's economy.

The spell which caused the destruction was a Roman Catholic spell, based on the legend of the House of Loreto. The legend concerns a house in a certain city in Italy, in which the Virgin Mary was said to have lived. The house was said to disappear and appear on its own, teleporting twice in the past. The spell for 'moving a building' had an incomplete effect on the tunnel, moving a single portion unnaturally and cracking the tunnel. The spell is likely derived from a fragmentary analysis carried out by the French king Louis IX, who visited the original House of Loreto.

The Eurotunnel bombing caused considerable chaos in the market, and an increase in air and sea traffic to compensate for the loss of the land route. The delays in transportation resulted in a negative impact on the British economy, as well as the French economy. Some French groups blamed England for cutting off the route and made retaliatory plans.

Suspecting the French government and with the possibility of Magic having been used in the attack, the British Royal Family called upon Index Librorum Prohibitorum to analyze the site of the bombing to determine what spells might have been used. While Index and Touma were flying to the UK on a Sky Bus 365, a group of French terrorists attempted to hijack and down the plane but were thwarted. The attack had the effect of grounding the Sky Bus 365 and other passenger planes, adding to the problems caused by the loss of the land route.

After the briefing at Buckingham Palace, Index travelled with Princesses Carissa and Villian to the Eurotunnel terminal in Folkestone. Shortly after their arrival at Folkestone, Carissa received the Curtana Original from New Light and initiated her coup d'état. Inspecting the partially flooded tunnel, Index identified a Roman Catholic spell based on the legend of the House of Loreto as the cause of the destruction. Satisfied with confirmation that it was a French-based Roman Catholic spell, Carissa ordered military action against France before having Index knocked out.

The French president later contacted Carissa, stating that they should cooperate regarding the Eurotunnel terrorist attack. Carissa dismissed his desperate attempts at negotiation, exposing France's actions against England, sinking a French nuclear submarine in the Strait of Dover and threatening him with a retaliatory missile strike, ending the call by suggesting that he switch out with the Maiden of Versailles.
