Forerunner crystal

The Forerunner crystal, referred to by the Covenant as the Fragment of Divinity, the Shard of the Gods, or the Holy Light, was of incredible potential, capable of warping space, energy, gravity, and even time and slipspace. It was hardly understood by the UNSC forces who found it, but was a prize that the Covenant were extremely eager to obtain.

History
John-117 had returned the crystal to ONI personnel. Dr. Catherine Halsey and a team of scientists took the liberty into studying the crystal. Vincent knew that she was capable of making it tick.

By 2560, ONI and LEGION worked together to find the other remnants of the crystal. During this time, Vincent studied the shards of the crystal and contained what was left in a container till he found the remnants of the crystal. Vincent had heard about a second crystal located in a the museums mineral and gem section on Pandora and had ordered a hit squad to steal it for research purposes.
