Magic Cue Ball

The Magic Cueball is an item in Homestuck. Unlike a classic Magic 8-Ball, it always reveals the truth to its owner and makes predictions with alarming precision and specificity. Unfortunately, and also unlike a Magic 8-Ball, it lacks a portal on its surface that allows you to view the prediction. Because of its covered surface, only those with some sort of vision eightfold would be able to recieve anwsers from the item. In Hivebent, it is revealed that Vriska Serket was in posession of a Magic Cue Ball in the past, and was able to recieve answers from it because her customised lens could see through the surface of the ball. The ball ironically led to her losing her lens (and eye used to view through said lens), as well as her left arm, soon after being introduced.

The item was owned by, and supposedly, extremely important to Doc Scratch, as he blew up the orb after finding out Vriska was in its possession.

As of yet, the only known orb on Earth is owned by Jade, however her copy may be a cheap toy.
