In the third week of March 1930, on Monday Morning, two weeks after the incident happened during the duplication of the newly created crystalline white wisdom cube, Lizzy's unexpected actions, the freshly balanced law and order from the Universal Law, and the expected plan created by Accel using Time Manipulation Magic died down as Accel is currently being monitored strictly due to being categorized as a threat instead of hostile.
As for Lizzy, she was released from the underground prison but was placed there by a limitation created by the power of the magical wisdom cube that is fused with mana. At the same time, Accel and Lizzy's most powerful skills have been sealed, and their abilities and attributes can be used at 25% of their original state. They both are now under strict lockdown as they are allowed to move to their designated house from Eagle Union for Accel and Sakura Empire for Lizzy.
As they are given some peaceful time something is lurking at an unknown location in the Bermuda Triangle. An unknown deadly place that no one enters and also the perfect place where the Siren Nation was created as their secret main base, after the siren started getting pushed back to the use of wisdom cubes they created a secret stronghold or a Siren Nation for increasing their power and connect communication from their original world or those different timelines of the World of Azur Lane.
Actually, the Sirens didn't really get pushed back they did it intentionally because since each timeline are same but different future they had to do this, the reason is unknown. Since they are from the previous timeline that no one knows yet, they created the very same stronghold in the Bermuda Triangle (I made it up). Only sirens can enter the Bermuda Triangle due to their combined alien technology and the new power that was allowed from the Universal Law, the power to harness magical abilities and mana.
The Bermuda Triangle is always covered with storm clouds or mist that cannot be seen through it because the Bermuda Triangle is covered with Mirror Seas/Spaces, a perfect disguise that even the Azur Lane Alliance cannot discover even the arrival of the otherworlders and the creation of the Void Dominion. When arriving inside the Mirror Seas, there will be a huge futuristic alien technology gate will appear, this huge gate or fortress is the entrance of the Siren Nation.
The first introduction of the Siren Nation is the Heart of the Nation, the Supreme Authority Center where the highest command governs the intelligence that oversees all Siren operations. The Supreme Authority is a massive fortress city with endless towers of advanced machinery and magical energy being imbued altogether. It is heavily protected by layers of reality distortion, Mirror Seas, and Enforcer-Class Sirens.
The purpose of this Supreme Authority Center act as the control hub for Siren forces across all timelines, coordinate experiments and large-scale operations, and store data from all Siren programs and alternate realities. Inside the massive fortress city, there is the Command Spire where the central tower is located and where those Elite Sirens, Arbiters, Enforcers, and lastly the War Protocol Fortress have their important meetings and discussions.
Next is the Temporal Nexus a facility allowing communication and synchronization between Sirens across timelines, though the communication is very unstable due to the Universal Law interfering with their communication lines because they don't belong at the World of Azur Lane or because of the prohibition for exchanging informations. Lastly, at the massive fortress city, the Reality Anchors are the devices that stabilize the Supreme Authority and the Siren Nation within its dimension, meaning keeping the Mirror Seas intact without having problems with the Azur Lane Alliance and the Void Dominion knowing their location.
In the Inner Part of the Siren Nation is where the Siren Military Headquarters is located, though it is not necessary to do training like how shipgirls from the Azur Lane Alliance do because Sirens are based on commands through communication using coded or data text that they are given except for those Sirens who have intelligence that training is needed to increase their abilities and skills both from battle and strategic operations.
Not only it's for training for the Arbiters, Enforcers, and the Elite Sirens, but it is also where the facility for production for Mass Produced Siren Models, Executor-Class Sirens, Tester Elite Sirens, and Purifier Elite Sirens are created and it was called the Fleet Assembly Yard. Because of their vast resources of Mirror Seas, they train using Combat Simulators inside a small pocket world where endless and nonstop battles between them for training purposes.
And lastly is the Genesis Lab where they increase improvement or something lacking on the Sirens Weaponry or Riggings. Beside the Siren Military Headquarters is the Memory Archives where they store important data that I do not know. The rest of the Siren Nation is top secret due to lacking information, but there are other fortresses aside from the Siren Nation that are living on a permanent and unable to deactivate the Mirror Seas.
In the third week of March 1930, on Tuesday a large-scale operation commenced by the Siren Nation, a vast amount of mass-produced siren models launched an attack on the Void Dominion's main branches and soon towards their main base, and because of that the Azur Lane Alliance took notice about the attack and made a decision to watch them first before making a move.
In the third week of March 1930, on Wednesday, mass-produced siren models managed to destroy more than 10 main branches of the Void Dominion but were annihilated as the higher branch and officers started their move, the Supreme Authority Center commanded the Executor-Class Destroyers, Light Cruisers, and Heavy Cruisers to attack together with the new mass-produced siren models.
In the third week of March 1930, on Thursday to Sunday, mass-produced siren models and executor-class sirens that had destroyers, light cruisers, and heavy cruisers managed to destroy over 25 branches and killing more than 1000 otherworlders that were either from the higher branch or officers-in-command.
In the fourth week of March 1930, from Monday to Friday, the large-scale operation was halted because the Void Dominion was now sending otherworlders that had strong power and abilities if you compare them and Accel, they are stronger than him by just 5%, despite Accel's abilities and strength is being cut off by 75% by the Universal Law. Because mass-produced siren models take 5 to 10 otherworlders to defeat due to their strong alien technology and the combination of magical attributes.
When comes to the Executor-Class Sirens it takes about 25 to 50 depending on the type of sirens they are. Destroyers take about 25 more, Light Cruisers take 35, and Heavy Cruisers take more than 50 otherworlders. But, the Supreme Authority Center commences another attack with the uses for Battleships and Aircraft Carriers making the Void Dominion lose about 45% of their manpower, because of that they had no choice but to use stronger abilities knowing the fact that the Universal Law might interfere, and give punishment to impose limitations after using it.
In the fourth week of March 1930, on Saturday Morning, the Azur Lane Alliance will have a conference meeting at the main base of Azur Lane together with the two troublemakers, Accel and Lizzy. They will join the conference and/or either they will participate in the operation regarding the Siren Nation and Void Dominion.
