The Viridian Fungus of Yoth

A palely glowing parasitic fungus that grows on anthropoids and similar creatures with chitinous exoskeletons, it is slain by sunlight. When the venom of creatures infested with the Fungus of Yoth is introduced to the bloodstream it acts as a powerful narcotic and induces vivid, euphoric hallucinations of bizarre blue and green vistas of a lifeless alien world, much of it composed of numberless tiers of complex, ornate architecture. Strange glyphs can be viewed within some recesses of the aforementioned architecture and some sorcerers have claimed that they divined certain potent alien incantations from these glyphs. Occasionally a user of Yoth venom will have the sensation of being viewed and hunted by a vague malevolent force.

Irrationalist Frequencies

Irrationalist Frequencies are violent, crushing audial waves and tones that will temporarily transform sentient listeners into unthinking, instinctive beings that exhibit insane behavior yet often possess predatory cunning equivalent to their normal intelligence. These frequencies must be extremely loud to have any effect and are usually generated by machines custom built for the purpose by chaotic technocrats, scientists and sorcerers.

Although Irrationalist Frequencies may have been developed as a sonic weapon by the Ancients, some Men, especially those of chaotic inclinations, revel in the mindless state induced by these sounds and will attend secret gathering in order to expose themselves to them. Some even become addicted to Irrationalist Frequencies and many avant-garde artists secretly rely on the state induced by these frequencies to produce their bizarre creations.

The Blue Radiance of Erysh

An extradimensional radiation utilized by Sorcerers and the like to induce awareness of higher order dimensions, The Blue Radiance of Erysh is invoked by use of a apparatus of prisms and rods. The radiance itself overpowers all other illumination, and resembles ultraviolet "black light" illumination. Shadows are darker and patterns dance in the corners of one's eyes.

Although it is an exceedingly potent tool for the purposes of meditation, divination and sorcerous research, those who make frequent use of The Blue Radiance of Erysh are often subject to obesession and madness; with intense, frequent exposure users becomes canker-ridden and anemic.
