In the past, a divining tool known as a PSYCHOSLATE was used to feign precognition, but the PSYCHOSLATE's rough, cylindrical shape, cut from rough, cylindrical life, served poorly for its purpose. The PSYCHOSLATE's form factor was then cast into that of a crystal ball, a staple tool to augurs and oracles alike.
Eventually, due to the expansion of the Alternian empire upon the culture which created it, augurs and diviners were stationed within platoons of Alternian troops, guiding troops to foretold victories using their visions. As Alternian troops won, their augur's crystal ball would be decorated in its colors, bearing the insignia of the platoon.
This specific crystal ball bears a single figure eight etched into its surface, an homage to the GAMBLIGNANTS that you so adore. The traditional way this tool is made is with blue-dyed water, floating a 20-sided die within it. The faces of that die spell out vague portents, fortunes. No such die floats in yours.
The blue water typically resembles the blood of your species, but this specific iteration is filled with the condensed waters of the clouds of Skaia, which serve the same purpose as the die. To those who dream on Prospit, the MAGIC 8 BALL provides a useful service: true visions of the future.
