"All of creation cares not whether you live or die."
|“|| He has no name. At least none he has ever given. He is known as The Horsemaster. Custodian of the far fields. When he is at rest no being has known greater serenity. And when called to arms... no being is swifter at bringing everlasting darkness... save for me.|
— Death describing The Horsemaster
The Horsemaster is a mysterious being who watches over the herds of horses on a world known as The Far Fields. He is the one who gave each of the Horsemen their own mounts when they came to him. Death went to the solemn tamer so he can open a serpent hole that leads to Earth for him since the Charred Council did not issue his assignment.
|“|| Your causes have always been just Horsemen. I have no reason to doubt your word now. But know that the Charred Council has little forgiveness for defiance. And when the Heavens tremble with rage... It is the Earth that suffers.|
— The Horsemaster to Death
Death describes the Horsemaster as a being of immense serenity but, when enraged, he is very quick to the kill. He also deeply loves his horses, including those that belong to the Four Horsemen. He is willing to help Death as he knows that the Rider's causes are always just but is wary of The Charred Council's wrath as the Old One knows they are not to be trifled with. The Old One also shows a certain compassion for The Third Kingdom, as he stated to Death whenever heaven and hell rage it is always the Earth that pays the price.
The Horsemaster has extremely keen senses, being able to intercept Death, who is well known for his agility and speed. He is also able to open Serpent Holes. He is also considered by Death to be one of the most dangerous beings in the universe, as he claims that none save himself can bring about "Eternal Darkness" faster than The Horsemaster.
