When the calamity that created the @The Grand Scar happened, it was through the southern edge of an Ocean. The Grand Scar carved a massive canyon to the mantle, and the ocean was drained into underground fissures. Repressurized and superheated some of this water makes it way back up through steam-fissures in the @Fissure-Rocks Wasteland .
Left behind after the water left the ocean was decay and over time this decay mineralized into a top crust of the Spice. Undiscovered so far The Spice is a mineral combination that can be filtered to create reality warping elixirs such as the @Elixir of Spice.
@Elixir of Spice. These Elixirs can change things. Powerful in essence those who control the Spice could potentially control the world. Reality-Warping Elixrs can be used to transport the imbiber to any location on any world at any time. Reality-Warping Elixirs can be used to increase attributes or learn free-use spells. Reality-Warping Elixirs can be used to make temporary conditions permanent.
