Attack on the Queen Britannia

The Attack on the Queen Britannia was a battle which occurred one December morning in the current year of the story timeline, shortly after the Crowley's Hazard invasion of the United Kingdom.

Taking place in the Irish Sea, near to the, it was an assault carried about by British forces and several groups from Academy City on the hijacked Queen Britannia, in order to prevent Coronzon from using the stolen Honours of Scotland to seize control of the United Kingdom's magical system and performing the Ceremony of Mo Athair which would have resulted in the destruction of the world.

Coronzon
Around the time of the Golden Dawn's downfall, Samuel Liddell MacGregor Mathers summoned the Great Demon Coronzon, with orders to bring Aleister Crowley, the instigator, to ruin. Coronzon later appeared before Aleister during a summoning experiment in the Sahara desert in 1909, but was prevented from carrying out the late Mathers' command and was driven off. Afterwards, the demon secretly travelled from Africa to the United Kingdom and assumed the identity of Lola Stuart, creating a physical body to act as its primary avatar. While Aleister survived his supposed end in 1947 and continued his plan as Board Chairman of Academy City, Coronzon manipulated events while acting as Archbishop of Necessarius, both to fulfill its contract with Mathers and its own desires as the embodiment of natural breakdown and dispersion. The two would continue to plot in the shadows for the remainder of the 20th century.

On December 11th, Coronzon ambushed Aleister while he was knocked out following his battle with Kamijou Touma, in order to infest him and usurp control over Academy City. The demon also taunted Aleister by claiming to be possessing the body of his second daughter Lola. This attack resulted in the diffusion of Aleister's alternative possibilities, the Crowley's Hazards, across the world and their subsequent invasion of the British Commonwealth, in response to Coronzon's actions, with the prime Aleister shifting his consciousness to the body of one of them. Failing to seize Academy City, Coronzon ended up temporarily sealed within the shut-down city while Aleister pursued her achilles heel in the United Kingdom - the corpse of her contractor Mathers.

Facing Coronzon's anti-Crowley measures in London, the Divine Mixtures and grimoire-based recreations of the Golden Dawn, Aleister was eventually forced to unlock Academy City's technology to escape from death at the hands of the reproduced Mathers, resulting in Coronzon breaking free from the seal. Coronzon flew from Academy City to Edinburgh Castle, arriving as Aleister had Mathers' real corpse ready to use the connection against her, but was able to use her previous deception to trick Aleister, stabbing her and using the opening to burn the corpse. Released from the contract, Coronzon was free to enact the destruction of the world which she desired, naming the planned ritual the Ceremony of Mo Athair, in reference to her former contractor.

Honours of Scotland
The Honours of Scotland are a set of Scottish royal treasures, consisting of three regalia; the Sword of State, the Coronation Crown and the Ruling Sceptre, together with the Stone of Scone. The three regalia and the stone, a combination of three and four, form their own magical system, similar to the system symbolically rooted in the three power, four region structure of the United Kingdom and governed by the Curtana. As the spiritual items form an alternate foundation for the control mechanism, they can be used together as an alternative control for the UK's magical system, though this is only possible if the Curtana's control is unstable. The ideal position for their usage in this manner is at a point equidistant from the centers of the UK's four regions (England, Scotland, Wales and Northern Ireland) - in the middle of the Irish Sea.

With the Curtana-controlled system still unstable following the damage to the Curtana Second from the clash of Curtanas during the British Halloween,  an opportunity was created for the Scottish royal treasures to be used in this capacity. With the threat posed by the Crowley's Hazard invasion of the United Kingdom, the evacuation of the British Royal Family from London to Edinburgh was partly to prevent the Honours, stored in Edinburgh Castle, from falling into the wrong hands.

Queen Britannia
The Queen Britannia was a luxury cruise ship and floating fortress which was built in order to carry the British Royal Family in comfort and safety across the seas, in order to perform large-scale rituals at 53 predetermined points throughout the territories of the British Commonwealth, aided by the amplifying effects of its central temple. The ship served and protected the royal family for many years, though as necessary diplomatic trips came to be made by plane, the ship came to mean more as a show of force and technological might than as a vehicle.

After being decommissioned, the ship was moored in a harbour in Edinburgh as one of its major tourist attractions. As forcefully dismantling the ship might have resulted in a highly destructive rebound, it was instead intended that the mental noise from the tourists' thoughts would gradually neutralize the magical symbols over time, though it was estimated that the process would take over 1200 years.

Recent Events
In the early hours of morning before the battle, although the threat of the Crowley's Hazards was past, the invasion and the surrounding events had left the country in a unstable situation. Following a pursuit on the roads between London and Edinburgh by the recreated Golden Dawn, the royal convoy arrived at Edinburgh Castle, followed by the groups from Academy City, with Coronzon arriving not long afterwards.

Immediately after Coronzon stabbed Aleister and released itself from the bonds of its contract, Kamijou Touma faced the demon, but was soon grievously injured by her Magick: Flaming_Sword, only being saved through the wounded Aleister's intervention. Accelerator, having contracted with Qliphah Puzzle 545, briefly clashed with Coronzon before the demon left the graveyard to seize the Honours of Scotland beneath the castle. Easily overcoming the knights and Queen Elizard, Coronzon obtained two of the regalia and the Stone of Scone. The Sword of State ended up in hands of Hamazura Shiage, who was looking for a way to revive the recreated Dion Fortune, who had been reduced to cards following the clash between Aleister and the recreated Mathers, and when confronted by the demon, made a deal to assist her in return for a way to bring Dion Fortune back.

Coronzon's Preparations
At some point prior to the events at Edinburgh Castle, Coronzon (in her guise as Archbishop Lola Stuart) had made arrangements for the Queen Britannia to be moved from its mooring in Edinburgh. As the ship was a valuable cultural asset and the Irish Sea was comparatively safer at that point than the east side of Scotland, which bordered the sea leading to the European mainland and was therefore under threat from the Crowley's Hazards, the security crew likely didn't question the order.

Charge across the Ice
Throughout the battle, Index and Karasuma Fran monitored the battlefield from above with Fran's Bunny Grey balloon, communicating with the British forces.

Kamijou Touma and Misaka Mikoto
Riding on the A.A.A., Kamijou Touma, Misaka Mikoto and Othinus managed to get past the Aethyr Avatars and rode up the side of the ship, with Aleister's group passing by on their way in at the same time. Arriving on deck shortly before the tornado struck the ship, they entered through a different watertight door. They decided to head for the wheelhouse in order to interfere with the ship's heading and prevent it from reaching its destination, fighting the Aethyr Avatars along the way.

Accelerator VS Nephthys
After a few hits from the ice tornado against the ship, seeing that it wouldn't accomplish much, Accelerator had Qliphah Puzzle 545 complete her manifestation and broke into the ship. He decided to head for the engine room to break the propeller shaft and immobilize the ship, but before he made a move, he encountered Hamazura Shiage, bleeding heavily due to refining magic power as an esper in order to revive Dion Fortune. As Accelerator prepared to swat him aside and continue on, he was kicked by Nephthys in a surprise attack through a wall and then tackled through another wall into the ship's opera house.

In the subsequent battle, Accelerator thwarted Nephthys's initial attempt to use her tears on Qliphah Puzzle 545 again by breaking a sprinkler. Nephthys was unaffected by his next attack and subsequently made use of the water herself, dropping it down as a blade. Finding his reflection wavering from the water partially interfering with the electromagnetic waves and being struck by a piece of debris, Accelerator was forced to disperse the water but in the process created an opportunity for Nephthys to use her tears again. As Qliphah Puzzle 545 tried to contain her power as it was sent out of control, she was contacted by the Will of the Misaka Network through her connection with Accelerator and received assistance in turning things to his advantage, realizing her essence as a guide to the Abyss. Through this, Accelerator became capable of dealing lasting wounds against Nephthys.

The clash ultimately ended with Accelerator bloody from the side-effects of relying on something like magic as an esper and Nephthys tangled in the bars in the ceiling for the stage lights.

Hamazura Shiage and Takitsubo Rikou
Immediately after being saved from Accelerator by Nephthys, Hamazura had another encounter as foretold by the Magic God, this time with his girlfriend Takitsubo Rikou. He soon learned that she had been tricked by 'Anna Sprengel' into accepting a grimoire-derived module, an indirect and apparently safe way for an esper to use magic, in the belief that she could relay the method of modified scrying to Hamazura and prevent him from dying from the side-effects of using magic conventionally as an esper. Instead, 'Anna' intended to exploit her in order to eliminate Hamazura, using Takitsubo and her ability in order to guide the combat module's attacks.

With Takitsubo powerless to stop the crystal ball's attacks, Hamazura evaded the attacks and tried to free his girlfriend by breaking the crystal ball. His attempt to destroy the ball was unsuccessful and he was cornered, but enough time had been bought and mana supplied for the grimoire recreation of Dion Fortune to reactivate. The manifested Archetype Processor swallowed the crystal ball, distorting it from its original form and freeing Takitsubo. As Hamazura caught Takitsubo as she collapsed, Dion Fortune took form once more.

Aleister Crowley VS Niang-Niang
Shortly after getting aboard the ship with Mina and Lilith, Aleister determined the route to the temple and the likely elements of the 'password' required to access it. Before they could carry out any attempts at divination, they were approached by Niang-Niang, who was looking for a fight.

Their clash eventually led to the ship's kitchen, with Niang-Niang losing on purpose and helping Aleister by making it so that the collateral damage from the battle indicated the necessary symbols for accessing the temple, in return for Aleister facing her head-on despite already being wounded. Aleister and Mina subsequently made their way to the elevator in the central storeroom, where Coronzon's Aethyr Avatars attacked them. However, the two easily dispatched them and made use of the hair as footholds to climb the shaft and reach the temple.

Aftermath
After being split in half, the Queen Britannia was left slanted and sank in the half hour following noon. The various groups from Academy City took advantage of the situation created by the sinking in order to slip away, though Mina Mathers recovered the Scottish royal treasures and returned them to Queen Elizard before leaving. Kamijou Touma escaped immediately after the ship was blown open and fled across the ice, in order to prevent the dangerous and now-unsealed entity from killing anyone.

As the dying Aleister lay in the ruins of the temple, Madame Horos approached her, still posing at Anna Sprengel. However, Aiwass had been waiting for this opportunity and ambushed the fraud, successfully restoring the real Anna Sprengel to her body, but getting an arm to the gut for taking so long. After a brief conversation, the two left under a shroud of invisibility, with Aiwass advising Aleister to keep her silence to avoid dragging anyone else down with her. Accelerator then arrived with Qliphah Puzzle 545 and spoke with Aleister, with his vengeance looking like it would go unfulfilled. Handing over the cell phone she'd used to remotely access Academy City's technology, Aleister left Accelerator with the full authority of the Board Chairman, telling him with her last breath that he could achieve his vengeance against the adults in another way by taking control and creating the kind of Academy City where those remaining could smile together.

At 1.05 pm, Kanzaki Kaori discovered Aleister's body floating in the water and confirmed her death. The corpse was subsequently recovered, with Elizard requesting that it be treated with care, intending to give her a state funeral for helping them stop Great Demon Coronzon and to partially make up for the mistreatment Aleister had experienced from the United Kingdom in past.

However, neither Aleister or Coronzon were fully dead. After the blow to its soul, Coronzon's consciousness clung to her physical body, but to her horror, she found that Aleister was now in control of the body, due to a combination of Aleister's curse of failure, the influence of sparks coming back to the demon and the fact that the contract from the 1909 summoning was not actually annulled. After cutting her hair short and considering the overall situation, Aleister decided that she would remain hidden in the backstage beyond magic and science for now, before turning her attention to the matter of the entity lurking within Kamijou Touma, the seal of which was now broken. Meanwhile, Touma continued to flee, even as Index called to him from above, with Anna Sprengel and Aiwass looking on.

Given that the Queen Britannia contained a large number of antiques and artwork, it was expected that professional divers would be searching the wreck in due course.
