Crystal Orb (InstanceTopic, 24)
From Compile Worlds
The Crystal Orb is pretty much exactly what it says on the tin. It is an object of immense power, created to be a plot device-slash-Mac Guffin in Sonic RPG. The Orb brims with immense power, and anyone wielding it can eventually become capable of tossing around it's magic like a moron, including the Death Bolt. In Sonic RPG's sequels, it is revealed that the Crystal Orb is actually an imprisonment for the demon Cornelia, and that the orb itself has no real power other than hosting within it an endless, empty space for the souls trapped in it. Being made of crystal, the orb is quite fragile, thus making it a literal glass cannon. If one is to shatter the orb, it would break into countless pieces, as fragmenting the souls trapped within it.
The Orb also exists in the fanon that the Sonic RPG series is based on, but it's importance has been demoted over time.
