Babd Catha Forerunner vessel

The Babd Catha Forerunner Complex was an ancient Forerunner complex on the planet Reach. It was located underneath Sword Base on the Babd Catha Ice Shelf. It was the home to one of Dr. Catherine Halsey's labs, and had evidently been under excavation by the Office of Naval Intelligence for some time.

According to Dr. Catherine Halsey, the complex held secrets that could turn the tide of the Human-Covenant War — a "latchkey" discovery that Halsey compared to the invention of the conical bullet and the Shaw-Fujikawa Translight Engine. However, when the Covenant began attacking the facility on August 29, 2552, the decryption was only partially complete. Using Wolf Spider turrets, Noble Team was able to hold off the Covenant for long enough until Halsey could finish the decryption.

Exactly what data Halsey discovered within the complex was never revealed, but it may have been the location of or information about Halo as she refered to what was discovered as being a place that had to be traveled to where something that might help fight the Covenant existed.

Trivia

 * The Babd Catha complex marks the second large Forerunner complex on the planet Reach, perhaps suggesting that Reach was somehow important to the Forerunners.
