|Heart of Darkness|
The Heart of Darkness is a small, black diamond first mined on the desolate world of Apokolips. Millennia ago, it was cut and shaped and used as a tool to crush those who opposed Apokolips' ruler Darkseid. The diamond was later mystically tethered to the demonic agent of vengeance known as Eclipso.
At some point in time Vetis came across the spirit of vengeance, Eclipso. What happened to the two during their encounter is unknown other then Eclipso being sealed within the Heart of Darkness and Vetis's change of nature.
