CIS-Necron Wars

The CIS-Necron Wars, also known as the Necron Conquest of the Outer Rim, or the War for a free Outer Rim was a series of minor skirmishes and conflicts between the ever expanding and ruthless Necrons and a Imperial splinter fraction the Confederation of Imperial Systems. The war lasted two years and cultivated in the splintering and destruction of the CIS after the Necrons destroyed the CIS main capital/headquarters on a massive artificial habitation known as the Disc.

The CIS were allies of the Resistance, and were suppose to aid them during the Battle of Crait, but the Necrons launched a massive invasion of the CIS mining world of Skywalker's Hope. Later the Necrons assassinated the CIS president of Kilos Virgos.
