The Prince They Named "Monster"

Thestrals are unusual to say the least; they live isolated from the rest of the world up in their mountains and rarely welcome outsiders for much more than tense trade arrangements.

However, they are quite the interesting race: visually they are a cross between a pony and a bat with large leathery wings and thick fur. But if one were to look a thestral in the eye then they would notice that the thestrals actually bear more resemblance to dragons than bats, in fact, many thestrals are skilled pyromancers. Their mountainous habitat lends itself well to their cave-dwelling nature and thestrals compliment this with great skill in digging. These talents combined make thestrals skilled blacksmiths and metalworkers whose creations are highly prized across the world.

No thestral, however, was a greater smith than the legendary Solid Steel, second only to the great forge-master Luna of Equestria. Solid Steel's creations would never break or dull, even after centuries of use, and he was more skilled in enchanting than any pony or deer, despite having neither horn nor antler with which to cast spells. Solid Steel commanded profound respect amongst all the creatures of the world and was forever known as Master of the Mountain.

This is not his story.

Some thestrals also carry the signature characteristics of wyrms, most prominently the sharp claws on the front of their wings. So sharp in fact that the aptly named Sharp Blade once tore an opponent limb from limb with nothing but his wings, losing an eye in the process, but becoming legend.

This is still not his story.

No, our story begins, as many great tales of Equestria do, with Princess Celestia and a cup of tea.
