While not all of the little people distribute or use faerie dust, it is used by many and worth examination.
Fig. 1 Common House Faerie Dust: The most common of all magical dust distributed by brownies, house elves and other home dwelling magical creatures. Frequently mistaken for ordinary house dust. Fastidious distributors of this dust will simply replace dust that has been 'cleaned' by the human inhabitants.
Fig. 2 Trooping Elf Dust: Found in mossy areas where trooping elves are known to parade. Difficult to find due to camouflage. Is distinguishable only by slight iridescent flecks.
Fig. 3 Geancanach Dust: This dust is particular to faeries who guard or live near hearth fires or fireplaces. This dust is named after one such faerie, the Irish Geancanach (not to be confused with the completely different creature, Gancanagh). This dust resembles fine soot and is prized by witches who recognize it's magical potency.
Fig. 4 Piggywiggins Garden Dust: Utilized by a species of garden faerie (the Piggywiggin) to promote garden growth. It is a fine mixture of pollen, seeds and some sort of a golden magical substance. Piggywiggins will freely distribute their dust if kept content and happy and on good terms with the farmer/gardener.
Fig. 5 Fairy Godmother Dust: This particular dust is comprised mainly of glitter. It is often more potent as a theatrical devise than magical tool. It is a favourite of Fairy Godmothers (who adore showmanship) to add pinache to their flamboyant spell weaving style.
Fig. 6 Frost Faerie Dust: One of the most difficult types of faerie dust to collect. This dust is mingled with snow and samples must be collected grain by grain. Distributed by cold climate faeries when temperatures reach a freezing point.
Fig. 7 Night Faerie Dust: Unique in its dark shimmering colour, night faerie dust is used sparingly by nocturnal faeries. The main magical uses for night faerie dust are to facilitate human sleeping and to protect dwellings from bumps and other naughty nighttime occurrences.
