Enemy-Alliance Dalek War

The Enemy-Alliance Dalek War was a war between the Daleks of N-Space, known as the Enemy Daleks, and those of the Mentor's World, known as the Alliance Daleks. Initially the Earth Alliance was allied with the Mentor‘s Daleks, however after six years of war Commander Kalendorf came to the realisation that they had merely swapped one dictatorship for another. He arranged a truce with the Enemy Daleks and joined forces with them against the Alliance Daleks.

Prelude
The Daleks invaded Mutter’s Spiral from the Seriphia Galaxy, resulting in the Second Great Dalek Occupation. Over the years the Earth Alliance was forced into retreat and the Daleks employed Susan Mendes as the “the Angel of Mercy” to improve slave efficiency. She was accompanied by fellow slave Kalendorf, who used his telepathy to sow the seeds of rebellion. After a decade of war, Earth finally fell to the Daleks. On Yaldos, Suz made a broadcast across the Dalek Empire and issued the telepathic trigger: “Death to the Daleks!” The ensuing rebellion threw the Empire into chaos. (AUDIO: Invasion of the Daleks, The Human Factor, “Death to the Daleks!”)

Beginning
Three months after the rebellion against the Daleks, the Dalek Emperor took control of Project Infinity and, using veganite mined from Vega VI over the course of the Occupation, sent a beacon into a parallel universe from Lopra Minor. The Mentor's Daleks responded by sending a delegation who, upon learning of their counterparts' many crimes, engaged them in battle (AUDIO: Project Infinity) and captured the Emperor. However, before he could be interrogated, he entered a state of inertia, (AUDIO: Dalek War: Chapter One) having transferred his mind to Suz’s dormant body, which had been stored on his flagship after she was stunned on Yaldos. (AUDIO: Dalek War: Chapter Three)

The Mentor identified Kalendorf, Alby Brook and Mirana as leaders of the human resistance and freed them from their Dalek-induced stasis aboard the Emepror‘s flagship. They formed an alliance against their universe's Daleks. (AUDIO: Dalek War: Chapter One)

First six years
Over the course of six years, the Alliance Daleks fought alongside Earth Alliance against the Enemy Daleks, who were led by the Dalek Supreme in the absence of the Emperor. The Alliance Daleks sought further allies and reduced the civilisations of those who refused to join them, for whatever reason, to Mediaeval or, in the case of Emmeron, Stone Age levels by destroying their infrastructure. These worlds became known as the Punished Planets.

Once the Enemy Daleks had been backed into the solar system, Kalendorf led an attack against them from the Courageous whilst Alby and Mirana rescued the still-dormant Suz from being executed by the Mentor, who had learnt that the Emperor's mind was locked away inside hers. (AUDIO: Dalek War: Chapter One) Unknown to Alby, this mission was part of Kalendorf’s plan to betray the Mentor and make a truce with the Enemy Daleks. (AUDIO: Dalek War: Chapter Three)

With the Alliance Daleks at an advantage and approaching Earth, the Enemy Daleks self-destructed their saucers and destroyed a quarter of the Alliance's fleet. The Alliance, looking to regroup, found that the Enemy Daleks had terraformed Jupiter and landed there, (AUDIO: Dalek War: Chapter Two) aware that a second wave of Enemy Daleks were near Venus.

On Jupiter, half of the humans with the Alliance were poisoned by Varga plants and began to attack the other half, leading the Mentor to relieve Kalendorf of command and demand that he be subject to brain correction on Lopra Minor. However, he managed to escape, leaving the Alliance fleet in a state of confusion which left them vulnerable to the Dalek Supreme's attack from Venus. (AUDIO: Dalek War: Chapter Three)

The tide turns
The Enemy Daleks captured Suz on the Defiant (AUDIO: Dalek War: Chapter One) with the goal of restoring the Emperor upon getting her to Earth. (AUDIO: Dalek War: Chapter Two) Having left the Alliance fleet, Kalendorf boarded the Defiant and agreed to join the Enemy Daleks, convincing Suz to broadcast a message as the Angel of Mercy which would turn the humans against the Mentor. Alby protesfed, forcing her to shoot him so she could carry out the broadcast. (AUDIO: Dalek War: Chapter Three) With the new alliance formed, the Dalek Supreme demanded Suz as a hostage and took her to Earth, telling Kalendorf that he would see her again.

The war continued for a number of years, with Kalendorf leading Enemy Daleks and Earth Alliance into battle against the Alliance Daleks, including on Mecros V. Eventually the Mentor transported him into her universe to discuss the stalemate that the two sides eventually reached. Predicting that the war would result in the death of all life in Mutter's Spiral, she talked to Kalendorf and, once he refused to rejoin her, ordered her Daleks to return to her world, ending the war. (AUDIO: Dalek War: Chapter Four)

Aftermath
With the Alliance Daleks gone, the Dalek Emperor, having chosen to remain in Suz's body, prepared to declare a new era of peace in Mutter's Spiral and to attack the now-outnumbered humans when they least expected it. Kalendorf pre-empted the breakdown of the truce and travelled to Dalek-occupied Earth where he was taken before the Emperor. He seized hold of her and briefly reawakened Suz’s consciousness to trigger a telepathic command he‘d implanted in her prior to surrendering her: “Victory or death”. This triggered a signal across the Dalek command net, which Suz was connected to due to the Emperor possessing her, which ordered every piece of Dalek technology to self-destruct. This destroyed the Daleks and devastated large parts of the galaxy, being remembered as the Great Catastrophe. Mutter's Spiral was entirely free of Daleks from either world.
