The Ilumnos Series
The Orange World is an infinitely vast desert.
This place is home only to lost souls and strange creatures. It is an in-between land traveled by the recently dead on their way to face judgement by the gods. Most travelers know to find the River Styx which will take them to Aaru, the Land of the Gods.
Rakshasa merchants set up small temporary camps with their large tents. They sell:
Gifts: for the Gods. Gold, jewels, gems, fine arts and crafts, etc.
Scrolls: Maps to locate the Land of the Gods and other places, spells to protect you from monsters, and spells to locate lost loved ones.
Potions and Powders: To clense the soul, to protect you from monsters, to hasten the journey
Mounts: Camels and other beasts to ride or carry a load.
Ilumnos and the Orange World
The Ilumnos Machine is located atop a pyramid with a flat top somewhere in the maze of dunes in the vast desert.
From Ilumnos one must use both the yellow aand red color crystals simultaneously to get to the Orange World.
