Battle of Islay

The Battle of Islay is the earliest known battle to have been fought during the British Halloween. It is fought between witches of the Coven Compass and the Knights of England in the Atlantic Ocean near the island of Islay.

Background
The British Halloween had just begun and the Knights of England had started taking over several institutions in the country, including churches. With the witches of the Coven Compass allied to Anglican Church, it is likely the Knights of England attacked them in order to prevent the use of the Coven Compass.

First phase
Despite the witches maneuverability with their flight, the witches of the Coven Compass know that they are sorely outclassed by the Knights of England that have been empowered by the Curtana Original. Smartvery suggests that they should have the Coven Compass advance outside of the United Kingdom's borders, farther from the island, as the Curtana Original's empowering effects on the Knights of England will only work inside the country's borders. From there, they can use the Coven Compass' large-scale flash spell to take the knights all out at once.

Here, 100 witches are led by Smartvery to try to lead the knights farther to the sea. However, they are intercepted by 100 knights coming out of the water, forcing the witches to attack. The knights also brought with them a sea fortress.

Overloading of Curtana Original
Prior to 2:30 AM, Anglican Church forces have contacted the Coven Compass in order to use its large-scale flash spell on Buckingham Palace as part of a mission in overloading the sword.

Despite still being in a battle, the Coven Compass fires their large-scale flash spell on Buckingham Palace with the assistance of the "relay-points" set up by the Anglican Church forces across the country in order to guide the massive amount of magic power. The mission is successful, with Curtana Original overloading and severely weakening Carissa and the Knights, likely a contributing factor on how the witches are able to turn the tide of the battle to their favor.

Second phase
By 3 AM, the resulting battle has damaged the fortress and has made it tilt due to the damage on its altitude control. In spite of this, it is still fully functional. The knights however incurred far much greater losses from the battle, with their sea fortress half sunk after having its sailing ability destroyed.

With the witches successfully leading the knights northwest into the sea outside of the country's border, they are able to successfully counterattack the de-powered knights. Despite the presence of knights still attempting to bring the Coven Compass down, the witch continues to protect it. Thus, essentially the battle has been already won.

Aftermath
With no apparent opposition from the knights, the witches are able to follow through with the Anglican Church's request of firing directly towards Buckingham Palace using the Coven Compass' large-scale flash bombardment as the opening attack against Carissa for the Battle of Buckingham Palace.
