Lopra Minor
Lopra Minor, a planet located in the Lopra system, was the site of a dimensional rift used by Project Infinity. It was here that vast amounts of Veganite were brought by the Earth Alliance to open a portal to alternate universes. The Daleks found out about the plan and invaded the system, hoping to contact a universe where the Daleks reigned absolute.
The Earth Alliance attempted to stop the Daleks, leading to a large interstellar battle. The Alliance forces, led by Kalendorf and armed with information taken from the Dalek Command Network by former Roboman Mirana, destroyed all of the attacking airborne Special Weapons Daleks with sub-orbital assault craft but not before the Daleks succeeded in opening the rift. (AUDIO: Project Infinity)
What emerged were Daleks with an overwhelming sense of order, who were horrified by the Daleks of this universe. The two forces immediately started a titanic war of extermination spanning two universes. (AUDIO: Dalek War: Chapter One, et. al)
