Toffa tells Link his grandfather's story about a pure white horse. It may be a descendant of the Royal Family's white stallion originally owned by Princess Zelda. It was said to have escaped to Safula Hill after the fall of Hyrule Castle to Calamity Ganon one hundred years ago according to local legend.
The white horse can be found at Safula Hill along the path that leads to the Sanidin Park Ruins. The horse is warier, requiring Link to crouch walk as slowly as possible while approaching it from behind. Link can wear clothing and use items that increase his stealth to make approaching it more easier. Three additional segments to the Stamina Wheel are needed in order to be able to tame this horse, otherwise Link will get throw off while attempting to ride it. Energizing Elixirs and Enduring Elixirs can be used if Link does not have the necessary stamina for it.
After taming it, Link can ride and bring it back to Toffa at the stable. Toffa will request to register it first before speaking to him. He is surprised that his grandfather was not lying and gives Link the Royal Saddle and Bridle. This equipment is inherited from his own grandfather, custom fitted for the royal family's white horse, which he will automatically equip to the horse.
He is in awe of the horse and tells Link that the sight of the Princess riding atop her white horse was supposed to be a beauty beyond words. He states that he has no doubts that it is the grandchild of Zelda's white horse. After the quest is completed, Toffa says if he was a little younger, he would ride that White Horse with a gal just like the princess.
The White Horse
- "The Hyrulean royal family that perished 100 years ago would sometimes ride atop white horses as a display of their divine right. This white horse may be a descendant of one once ridden by royalty."
- — Hyrule Compendium
The White Stallion has four strength stars, three speed stars, five stamina stars, and a wild temperament. Thanks to its five stamina stars, it has five spurs. This horse is likely a reference to the unnamed White Horse used by Impa and Princess Zelda to escape Ganondorf in Ocarina of Time. Toffa's story about Princess Zelda riding a White Horse is proven true in Link's recovered memories and Zelda is seen riding a White Horse at the end of the game. Like the Giant Horse and Stalhorse, the White Horse has its own Hyrule Compendium entry which reveals that members of the Royal Family of Hyrule rode white horses as a symbol of their divine right.
Royal White Stallions
It is suggested by Toffa and the Hyrule Compendium that the White horse is descendant of the Royal White Stallion owned by Princess Zelda of Breath of the Wild before she sealed Calamity Ganon in Hyrule Castle. Zelda's unnamed Horse managed to escape the fall of Hyrule Castle and began living among the wild horses of Safula Hill, where its descendant is supposedly found. It is possible that both Zelda's Horse and its descendants where protected by Zelda's power, and possibly Hylia whom Zelda is descended from according to legend as she is referred to as the goddess blood Princess by Kass and are directly stated to possess the blood of the Goddess by Impa, explaining the presence of its present day descendant.
This indicates the possibility that Princess Zelda's Horse was descended or a reincarnation of the White Horse used by Impa and Zelda in Ocarina of Time. This would make sense as the legendary horse Epona is also known to have several incarnations. The White Horse is shown to have great stamina allowing it to gallop even more than Epona. This resembles the White Horse from Ocarina of Time which was able to out gallop Ganondorf's Steed.
It should be noted that the White Horse's Compendium entry reveals that the Royal Family of Hyrule traditionally rides White Horses as a display of their divine right. Presumably the White Horse ridden by Impa and Princess Zelda in Ocarina of Time was one of these royal white horses which Impa and Zelda used to flee from the Gerudo King of Thieves.
