Dark Orb

The Dark Orb was a black, crystal ball that allowed Trogg to summon the demonic entity known as the Dark One. When the moon's rays were focused on the orb by means of a giant lens, the Dark One appeared out of it like green mist. Tails, Knuckles and Morain Blackthorn stole the Orb, then destroyed it by throwing it into the "non-existent space" below the Dimension Bridge, destroying the Dark One in the process.
