Once very rare, encounters with the Necron fleets are starting to occur more and more. Their technologly is superior to every other race, including the Eldar. In every encounter so far the Necrons have only been defeated by superior numbers of enemy ships. Fortunatly the Necron fleets encounted so far have been small in size, but what will happen if they ever attack in force remains to be seen.
Until very recently, almost all contact with the Necrons had been limited to battles fought on planets against a small force of Necron troops. From time to time, reports were made of strange spacecraft encountered on the edge of newly discovered systems. These craft appeared derelict at first but became active when approached. Now, the full alien might of the Necrons is released across the galaxy, destroying everything in their path.
