Cliff Striders were a species of large, winged, reptilian creatures found in Vvardenfell. They were related to Cliff Racers and Cliff Darters, and the three species coexisted contemporaneously. Unlike Cliff Racers, Cliff Striders had great difficulty flying despite their wings, and consequently spent their lives on the ground, while using their wings to glide from cliff heights. But this did not stop them from being a successful predator, as a carnivorous species, they would prey on much of the local wildlife, including man and mer. Their young were known as Cliff Skippers and were hatched from giant nest piles. Despite their aggressive nature, they were admired in Vvardenfell literature.
In the mid-Second Era, one Thetys Ramarys of Balmora, selectively bred the Cliff Strider for their wing strength, in the hopes that they would eventually be able to take flight and dominate Vvardenfell's skies. However, by the late Third Era, Cliff Striders had been exterminated by the Ash Blight, along with several other unique Vvvardenfell species. It was recorded that the physiology and behavior of the Cliff Strider was very similar to the hackwings of Black Marsh, and it is possible that they shared ancestry. Some historians theorize this possible divergence resulted from Dark Elves raiding Black Marsh for thousands of years to bring back things they deemed valuable, such as slave labor, livestock, and critters.
Several breeds existed but shared a commonality with their loud screeches and terrible smell. The most common was known as the Bitter Coast Cliff Strider. Despite their name, they were once found all around the island of Vvardenfell. Others were bred for their vibrant coloring, the Ascadian Cliff Strider was known for its beautiful blue coloring, and said to have a screech capable of scaring infants into silence. The breed from the Molag Amur area were known for their golden coloring, and having a squawk that was said to make passersby and horses bolt.
