Riders to the Sky

The Riders to the Sky Mountains,  also known simply as the Riders to the Sky and the Sky Riders during the late years of the 15th century DR, were a range of mountains located in the Old Empires area of Faerûn, between southeastern Chessenta and northern Unther. After the Spellplague of 1385 DR and until the Second Sundering of the 1480s DR, when the nation of Unther was returned to Toril, the mountains were part of the dragonborn nation of Tymanther.

Geography
The Riders to the Sky were composed mostly of hills, ranging between 3,000 and 5,000 feet (900 and 1500 mts. approx.) in height, with cliffs on the southern end. They were rich with mineral veins. After the Spellplague, the peaks of those hills were shrouded in perpetual mists originating from the nearby Methmere.

The Jade River fell out of the western slopes and flowed west to the Bay of Chessenta. It was named for its greenish color, the result of algae and caustic runoff of the grey dwarf mining works.

History
An aarakocra civilization had been living in the mountains since the ancient past.

The rebellious Alliance of Chessenta, under the leadership of the warlord Tchazzar, drove the forces of Unther out of Chessenta and beyond the Riders to the Sky Mountains in the Year of Flashing Eyes, 929 DR.

The Riders to the Sky became a popular target for Chessentan mercenaries, who hunted the local aarakocra for sport. Their raids eventually destroyed their civilization, sending them extinct by the mid–1200s DR.

In the summer of the Year of Lurking Death, 1322 DR, the Great Bone Wyrm Alasklerbanbastos swept down out of the Riders to the Sky and inflicted a reign of terror on Chessenta.

Circa 1357 DR, both the kingdom of Unther and the city-states of Chessenta laid claim to the Riders to the Sky Mountains, but the Chessentans were in no position to contest this.

Locations
The northernmost peak of the Riders to the Sky was Dragonback Mountain, a volcano that had been long dormant. It was the lair of Alasklerbanbastos, the Great Bone Wyrm, and a Cult of the Dragon stronghold.

By the mid–14th century DR, small mining outposts lay on the Chessentan side of the mountains. They usually sent their goods to Mourktar and Thamor in Threskel. The Untheric side was largely cleared lands.

In the foothills of the Riders to the Sky, far from habitation, stood the former tower of the mage Maxiladanarr Torstren. The secretive Magister destroyed it with fire and lightning in the Year of Lurking Death, 1322 DR, in order to fake his own death.

The ruins of the aarakocra civilization lay among the hills.

Fauna
There was a sizable population of monstrous creatures, such as the rare tuuru (pteranodons), which made their homes in the southern cliffs but could be found all over the range.

Inhabitants
Bandits and outlaw tribes lived on the eastern, Untheric slopes, using the hills as a base for raids on both Unther and Chessenta in the mid–14th century DR.

The western, Chessentan side along the Winding River was much wilder. Here, the range was inhabited by trolls who lived in villages on the surface and gray dwarves who dwelled in caverns below ground. The range was also home to various chromatic dragons, who occasionally claimed the riches dug out of the mines.

In ancient times, the hills were home to an aarakocra tribe.

Legends
In legends of ancient times, warriors of Unther were said to use the pteranodons as flying mounts. However, their size, strength, and weight made it unlikely that they could carry a human. Instead, unless larger breeds once lived, the legend was usually deemed a fiction.

A community of half-drow exiled from the Yuirwood in Aglarond, long before the mid–14th century DR, were rumored to survive in the Riders to the Sky, and to live alongside the trolls.
