Kryptonian black box
From Smallville Wiki
<P>
The Kryptonian black box was a device made by Kryptonians and the hard drive of the Brain InterActive Construct.
The black box resided within the Black Ship until it was removed by General Zod. It played a major role in his master plan to turn Earth into a new Krypton, and was able to remove the computer virus that Brainiac had unleashed before in order to wreak havoc all over the world. (see Dark Thursday)
Luckily, Clark Kent managed to split the black box in two pieces with his heat vision. Lex Luthor found one part of the box, and it was examined by Dr. Edward Groll, who quickly realized how dangerous the device was. It is unknown what happened to the rest of the black box. However, Lex's fragment held a huge amount of energy until it was recently absorbed by Baern and a pile of ashes was the only thing left. It empowered Baern enough to kill Raya. Baern's power, however, was absorbed into the Crystal of El and used to re-charge the Fortress of Solitude.
