Ancient Taurosian myth tells of a magical dragon reminiscent of modern-day Sandbirds, known to many as Flamingfeather.
It possesses immense speed and the characteristics of both birds and reptiles. It is known for its plumage of color of shiny molten copper but also dull green oxidized copper camouflaging itself in the green sand. Its wingspan is two times larger than its body. It flies high above the sands. Its tail is as long as the longest snake with fan-like feathers on the tip. Its eyes are large and darker than night.
It only appears during the day when the temperatures are extreme. Running and flying at insane speeds can be a sign of sandstorms to come or an oasis nearby. Summoning craters meters deep to create an oasis to nest in, they dive into the underwater caves at night. Fierce and dangerous, it's known for using its fiery breath to melt the walls of its crater to keep the water from leaking into the surrounding sand. This unique power, known to many as the "Flaming Feathers," creates caves and channels in the desert sands. It battles dragons on full moons. The heat of its breath is so intense that it can even evaporate metals. It has the magic to bend and shape the molten metal to its will. 
Legends of great rulers wield weapons from their magic-embued metals.
It is known to be sacred and believed to possess the power to bring forth water and create fertile land within the desert. Legends tell of leaders bonding and taming them. They obtained control of the elements and brought prosperity to their people and decimation to other lands. Many have tried to capture and tame one but have failed. The creatures are elusive and fierce, and their fiery breath makes them impossible to handle.
Many desert wanderers look for the paths created by the flaming feathers to find food, water, and shelter. In myth, it became a vital part of the desert ecosystem. Not only is it a symbol of life in the desert but a reminder of the harsh and unforgiving nature of the desert.
