The Alliance Daleks, so-named by the Earth Alliance to distinguish them from the Enemy Daleks during the Enemy-Alliance Dalek War, were Daleks from a parallel universe. They crossed over to N-Space at the end of the Second Great Dalek Occupation.
Their casings were equipped with implants to enable the Mentor to observe their experiences. Kalendorf once ripped a mutant out of its casing to talk to it without being spied on. (AUDIO: Dalek War: Chapter Four)
In a parallel universe, the Daleks were created by the Mentor on a planet other than their version of Skaro (AUDIO: Dalek War: Chapter Three) to bring about universal peace, which they achieved through force, eventually ruling the entire universe. (AUDIO: Dalek War: Chapter One)
The Dalek Emperor made contact with them from N-Space through Project Infinity, hoping they would assist him in replicating their conquest of the universe. However, the Mentor's Daleks were disgusted by the Emperor's crimes and began a war against his Daleks. (AUDIO: Project Infinity) They awakened Kalendorf, Mirana and Alby Brook from suspended animation aboard the Emepror’s flagship and put them in contact with the Mentor. The Mentor agreed to join forces with them and the remnants of the Earth Alliance against the Emperor Daleks. The Mentor’s Daleks were referred to as the "Alliance Daleks" as opposed to the "Enemy Daleks".
Over the course of the War, the Alliance Daleks secretly destroyed the infrastructure of any planet that refused to join them regardless of the reason, returning them to a Medieval or, in the case of Emmeron, even Stone Age level and creating what were known as the Punished Planets. (AUDIO: Dalek War: Chapter One)
The Alliance Daleks experimented with "brain conversion" (AUDIO: Dalek War: Chapter Two) and created the Demons, effectively advanced Robomen who were almost completely wiped out by the Enemy Daleks (AUDIO: The Demons) with only Morli, (AUDIO: Dalek War: Chapter Two) Elaria (AUDIO: The Warriors) and Galanar surviving. (AUDIO: The Demons)
After six years of war against the Enemy Daleks, the joint forces of the Earth Alliance and Alliance Daleks had pushed back the Enemy Daleks to a final stronghold in Earth’s system. However during their advance, Kalendorf made a deal with the Dalek Supreme and for the Earth Alliance to to fight the Alliance Daleks, having determined the Alliance Daleks were simply a more outwardly benign dictatorship. (AUDIO: Dalek War: Chapter One, Chapter Two, Chapter Three)
After many years of war, the Mentor ordered her creations to return to their own universe, believing the conflict would result in nothing but the extinction of life in the galaxy. (AUDIO: Dalek War: Chapter Four)
