Central data core

"It's kind of like a back-up hard drive for all the Replicators."

- Rodney McKay

The central date core is a secondary hardrive used for Nanite base coding. The core was responsible for everything the Asurans have done, including a directive to attack the Wraith. However, 10,000 years ago, after the Lanteans were defeated, the Asurans attacked the Wraith through a command from the date core. However, when the Wraith discovered this, they managed to have used the data core to shut down the Wraith attack code.

In 2007, the First Atlantis Reconnaissance Team were able to come into Asuras undetected to steal a much needed Zero Point Module. Rodney McKay was able to discover the core and its use purpose through Elizabeth Weir, who was infected by Nanites that were recently reactivated before their arrival. McKay managed to have used Sheppard and Ronon to upload the command to attack the Wraith via the data core.
