Although Cormyr claimed this land as part of its territory, it could not control it beyond where its soldiers marched. It was an inhospitable place for civilized humanoids and was home to orcs, goblinoids, and other creatures. Cormyr's monarchs long offered generous rewards for those who could establish and maintain settlements in the region.
Many legends told that the Stonelands were created circa −200 DR when Asram and Anauria attacked a magical realm that existed above the clouds of the region, called the Cloudlands, in order to escape the encroachment of the ever-expanding Anauroch desert on their kingdoms. The castles built above the clouds crashed down to the earth from the sky, creating the Stonelands.
In the Year of the Gauntlet, 1369 DR, Princess Alusair was operating in the Stonelands again, commanding a troop of twenty-four young noble knights pursuing a bold orc band that had raided a caravan east of Eveningstar. In six days of pursuit, they'd killed a hydra, a fire lizard, and three chimeras. North of Startop Peak, the knights impetuously pursued the orcs into an ambush, and a few were killed. Alusair rallied her forces to defeat the orcs, before deducing they served a dark naga and the Zhentarim, who had been charming and transporting monsters into the area. They defeated the naga and destroyed the gate before it could disgorge another monster. Alusair and the knights resolved to seek out and destroy the other gates.
Folk of northern Cormyr feared the Stonelands as a place that all kinds of monsters poured out of to harry them, from wolves to orcs to trolls, and even evil wizards and dragons. Other dangerous creatures that were known to inhabit the Stonelands included chimeras, fire lizards, goblins, hill giants, hobgoblins, hydras, ogres, and wemics.
A few varieties of dinosaur lived deep within the Stonelands, though all were small ostrich-sized species. These included deinonychus, fleshrakers, swindlespitters, and velociraptors. All of these species hibernated in deep rifts near earth nodes and volcanic flows. They were never known to race along the heights of the Stonelands or ventured far from the region, as they feared being eaten by dragons, dark horrors, or Zhent foulwings.
