Keeping track of time on the plateau was a hard, if not impossible task. In his spectral form, King Rhoam didn't exactly have a calendar or watch. Nonetheless, he could definitely feel the date approaching. Maybe it was his status as a spirit, or perhaps as former king, that allowed Rhoam to gather a sense of the magic acting upon the hoisted rock he currently called home—it didn't matter—he had a gut instinct that his daughter's knight was coming.
With this premonition in the back of his mind the old man began a slow trek from his cabin to the Shrine of Resurrection. After one hundred years of waiting Rhoam was finding it hard to refrain from checking the shrine daily; it was only this day in early spring when he saw the door's lights change from a faint orange to a radiant blue. And, after a quick gasp of elated surprise, the old king scrambled back down the hill to start a welcoming fire. Thankfully, he had already set up some firewood in the small corner of rock just down the path from the shrine. Rhoam readied his axe and took a swing at the flint. The sparks caught the logs, and within minutes he had flames. With a smile hidden beneath his great beard, the old man picked some fruit from the nearby tree. One of the boy's favorite baked apples would surely be the perfect way to welcome him back from his slumber, would it not?
Only a few moments passed until the door to the shrine opened with the distinct sound of creaking stone. Out of the door stepped a boy that didn't appear to be a day over seventeen. He was clad in a dirty, tan shirt along with some equally filthy, brown trousers. In spite of the state of his clothes, the boy looked impossibly clean. As he stepped to the edge of the cliff and overlooked the lush lands of Hyrule, the king felt a lump rise in his throat. For what seemed like hours the old man stared at the boy looking out over the plateau. Suddenly, it became clear to King Rhoam. This boy, who was wearing shoddy clothing terribly unfit for a knight, who had just woken up from one hundred years of a restorative coma, was still Hyrule's greatest hope for a future without calamity. Regardless of how little he remembered, and despite the fact he was missing the sword that used to never leave his back, this boy would defeat Ganon. The old man knew in that instant that Link would save his daughter.
…
Four shrines later, and the old man knew his time was fading fast. In the most simplest way, he was deathly afraid. Rhoam had the utmost trust in his former knight, but he was still not sure if he was ready to tell Link the full truth about the history they shared. However, it appeared as if he did not have a choice in the matter. The ethereal, green embers that marked his ghostly form were becoming brighter and brighter, while the image of his body was slowly turning transparent.
As he stood atop his perch on the Temple of Time, Rhoam was able to make out Link's figure on the temple floor below. It seemed that Link was able to decipher the old man's cryptic hint from earlier.
Link approached the statue of the Goddess on the ground floor, unaware that Rhoam observed him from above. The king watched as brilliant rays of light were cast upon Link as he kneeled before Hylia. A glowing, red heart materialized in the air above the boy; the old man watched in awe as it fell toward Link, who promptly absorbed it into his being in a bright flash of red. It was clear that the Goddess had just bestowed upon Link a gift of power. As soon as the heavenly light faded and the temple was left empty, Rhoam finally decided to call out to the boy.
"The blessing of the Goddess has made you that much more resilient, I see...Here I am...get up here—quickly!" Links expression was unreadable as usual.
Within a moment Link joined the old man in the steeple of the temple. His reaction to the man's teleportation from earlier combined with the way he was currently staring at the green wisps surrounding him made it obvious that Link was curious about Rhoam.
"Now then...The time has come to show you who I truly am."
And King Rhoam told his story to Link. He told Link of his position as King of Hyrule, the prophecy of Calamity Ganon, and how this calamity struck one century prior. He recounted the story of the Goddess-blooded princess with a holy power, and her appointed knight wielding the legendary master sword. He explained the excavation of the divine beasts, and the appointed champions of each of Hyrule's major races. And he described the betrayal of the guardians, the destruction of Hyrule Castle and the surrounding towns, the fall, and the resurrection of the appointed knight over one hundred years.
"That knight was none other than you, Link," the king revealed to the astonished boy.
And finally, Rhoam told Link of his trapped daughter, doomed to battle Ganon for over one hundred years, but destined to be freed by her appointed knight.
To the king's great relief, Link did not seem to falter whatsoever when he was finally asked to begin his journey to defeat the calamity. Link had lost his memories during his slumber, but it looked to Rhoam that his sense of duty and responsibility had remained.
Just like that, Link accepted the task thrust unto him without hesitation. Now all that was left for the old man was to point Link toward Kakariko.
...
King Rhoam looked on as Link leapt off the plateau and deployed his new paraglider. Link slowly floated toward the Dueling Peaks, and the king felt himself near the end of his span as a spirit. Of course the old man was slightly uneasy in leaving the mortal world. The fate of his country was riding on a boy of seventeen years. Yet at the same time, Rhoam was comforted by his confidence in one thing:
If anyone had the power to save Hyrule and Zelda, then that person was probably Link.
King Rhoam Bosphoramus Hyrule looked out from the plateau at the evil in his castle one last time before evanescing into nothingness, hopeful for the future of the land.
