Sand

Sand was composed of small grains of finely ground up stone and other minerals. Wind could drive piles of sand into piles or hills called dunes, which could cover hundreds of square feet. The strongest of winds could blow dunes large distances in only several days. Dunes always had a steeper slope on the leeward side.

Sandstorms were harmful to most creatures, where the driving particles would reduce visibility and chafe skin.

Powers
Sand was used as a material component in many spells of Faerûn, including color spray, Leomund's secure shelter, move earth, persistent image, sleep, and statue.

Reputation
The Lands of Intrigue were also called the "Empires of the Sands", but this was a misnomer, as only Calimshan had deserts and neither Amn nor Tethyr had any deserts to speak of.

In the Zakharan view of magic, many spells related to the element of earth were grouped into the province of sand.
