The legend of Gromak

In the era of the birth of the kingdom of men, his shield was the knight Argantor, whose valor knew no equal. His faithful companion was the stallion Gromak, clad in armor of star iron. In the saddle, they became a single being — a living embodiment of the storm, before which not only monsters but also demons trembled.
 
To crush him, the horned gathered an army. Only at the cost of incalculable losses did they manage to defeat Argantor. But Gromak did not run. Standing over the master's body, he desperately defended him until his last breath. The demons, seeing this devotion, retreated. After the battle, the horse hoisted the owner's body on itself and carried it to the capital. After that, limping, Gromak left the city.
 
The knight's body was buried in the royal tomb. Gromak wanted to be buried next to the owner, but they could not find him. However, to this day, on the fields of past battles, people and demons see a ghostly horse in star armor. They say it's Gromak's spirit. And he is not looking for peace, but for a new rider worthy of the legacy of the great Argantor.
