Legends in the Sand: The Sword of Dregoth
Windblown dust, ash, and silt accumulate in depressions to form dust sinks or silt basins. The largest known example is the Sea of Silt, but smaller sinks exist in almost any low-lying terrain. Even a light wind stirs the dust into billowing clouds. On calm days, a dust sink appears to be a smooth plain of pale gray or dun powder. Appearances are deceptive. The dust is too light to support a traveler’s weight, but it is thick enough to suffocate anyone who falls in. Some times, the ground beneath the powder is uneven, concealing a dangerous drop. One misstep, and a traveler can disappear beneath the dust.
Large bodies of silt often extend like the rivers of old into more solid terrain, following narrow channels called estuaries. Many estuaries of silt are shallow enough for human-sized travelers to wade with care. Very tall creatures such as giants can navigate correspondingly deeper silt; a giant can wade through silt 10 feet deep without difficulty.
Many large sinks and estuaries are sprinkled with islands of high ground, isolated from the “mainland” by stretches of dust of varying depths. Some of these islands are rocky protrusions just large enough to accommodate a giant or two, and others can support an entire village. Miles of silt have sheltered many islands over the years from the touch of defiling magic, and those islands remain surprisingly verdant.
