“ Yupiorite
Also called 'pale-yellow witch' by alchemists, this mineral is known to possess a peculiar attribute. When found, a Yupiorite will appear the palest yellow. Rather than crystalline in structure, Yupiorite occurs in weird, smooth, ovaline shapes, as if already carved by skilled hands to serve as ring or necklace ornaments. Yupiorite somehow detects and reacts to mood. When the wearer of the gem is content, calm, and happy, the stone will remain the palest yellow. As the person gets more excited, angry, or otherwise stimulated, the mineral will darken progressively to a dark corn-yellow in color. Why the gem reacts this way to sentient mood swings, is still debated by gemologists and alchemists alike.
It is said that the Elven Halls of Vala-Aluduwy are resplendent with wall-sized mirrors of pure Yupiorite, showing plainly and ironically, the emotions of everyone present, despite the Elven love of restraint and stoicism.
Aragdulose
'Cave-grass' or 'cave-pine' is a deep forest green in color, rare and often mistaken for other minerals, though otherwise mundane. Crystals form into tiny, ultra-thin, needle-like clusters by the hundreds of thousands, creating vast dark green bursts and structures, resembling evergreen conifers, if viewed by any sort of light. Despite its ephemeral shape, Aragdulose is only second to a diamond in hardness.
Dwarves are said to keep these mineral 'trees' in their homes, putting them up during festive family holidays, leaving presents beneath them, for kin to open.”
“ Arakis's zombie problem went largely ignored, because it was believed that the Shai-Hulud (sand worms) would effectively dispose of the undead walkers. Unfortunately the problem grew until the roving herds of sunburnt ghouls threatened the flow of spice. While observing one of the great reanimated masses over take a Harvester from the safety of an ornithopter, an Imperial Zoologists noted that the sand caked flesh eating revenants walked entirely without rhythm.
Shortly after receiving this report the Bene Gesserits claimed to have a solution to Arakis's hellish resurrections. They asserted to the agents of the great houses that the worms could be drawn to the walkers using an ancient sonic weapon. According to the sisters, exposing the zombies to an antediluvian ballad composed by the great master M. Jackson would force them to step in time.”
“ Believable magic, like ordinary physicis, operates according to some invariable laws that always result in some kind of cost or 'bounce back'. The grater the magic, the more it should cost the character physically, emotionally, and spiritually.”
