C-Deck/Legends

C-Block was a communications block on the flagship of the Super tactical droid Aut-O. It is in C-Block where the Separatist encryption module was contained. It is now supposed that all Providence-class carrier/destroyer ships have at least a variation of the C-Block.

Biography
During the Clone Wars, c. 20 BBY, the C-block was hacked into by the D-Squad, an elite group of droids put together for this specific task. C-Block contained a room with an encryption module that was stolen by the D- to decipher a Confederate transmission sent out by General Grievous.
