It was Pentecost in Camelot, and all the Knights of the Round Table were gathered together. The table was set for the great feast, and Arthur, as he always did, waited for something marvelous to happen before anyone began to eat.

Suddenly, thunder rolled through the hall, though there was no storm outside. The doors and windows closed by themselves, and a soft golden light filled everything — brighter than the sun, yet gentle on the eyes.

Then, floating in the air above the Round Table, something extraordinary appeared: a chalice covered with a white cloth that shimmered. The chalice poured out light and peace, and everyone who looked at it felt their heart fill with joy and love.

The vision lasted only a few moments, and then it vanished as mysteriously as it had come. The hall fell silent. Everyone knew what they had seen: the Holy Grail, the chalice that Jesus Christ had used at the Last Supper.

Sir Gawain was the first to speak, still dazed by the vision.

"Brothers, we have seen the Holy Grail, but it was veiled, and it has gone. So I make a solemn oath: I will ride in quest of the Grail until I see it unveiled, or die trying."

One by one, all the knights of the Round Table stood and made the same oath. One hundred and fifty knights swore to seek the Grail.

King Arthur, however, grew sad.

"My noble knights, I fear this is the last time we shall all be together. The quest for the Grail is dangerous. Many will ride out and never return, and the Round Table may never be whole again."

But the knights were determined. Merlin had foretold that only the purest and most perfect knight would find the Grail. Who would that knight be?

Among the knights who rode out was Sir Percival. He was young, pure of heart, and determined. But his story had begun very differently.

Percival had grown up hidden away in a distant forest. His mother, Lady Acheflour, had raised him far from everything, for his father and brothers had died in battle, and she did not want Percival ever to become a knight. But one day, when Percival was fifteen, he saw five knights riding through the forest. Their armor gleamed in the sun, and the boy had never seen anything so magnificent.

"Mother! Mother! I saw angels in the forest!" he cried.

His mother sighed.

"They were not angels, son. They were knights."

"Then I shall be a knight," Percival declared.

His mother wept, but she knew she could not stop him. She gave him an old horse and simple clothes, hoping he would soon come home. But Percival set out for Camelot.

When Percival arrived at Camelot in his rough clothes, riding his old horse, many laughed at him. But Arthur saw something special in the young man.

"Do you wish to be a knight?" Arthur asked.

"More than anything, Your Majesty."

Arthur took him in and trained him. Percival learned quickly, for he had natural talent and, more important still, a pure heart. He did not fight for glory or gold, but because he believed in what was right.

The years passed, and Percival became one of the finest knights of the Round Table. And now he was setting out on the greatest adventure of all: the quest for the Holy Grail.

Percival rode through many lands. He crossed dark forests where the trees whispered, passed through valleys where dragons slept, and forded rivers where mermaids sang. Along the way he faced many wicked knights and defeated them, rescued maidens from danger, and defended villages from bandits. But the Grail stayed hidden.

One day, Percival came to a wide river. On the far bank stood a magnificent castle on a hill, but there was no bridge anywhere. While he was wondering what to do, a boat appeared, rowed by an old fisherman.

"Do you need to cross, young knight?" the old man asked.

"Yes, sir. I seek the Holy Grail."

The old man smiled a mysterious smile.

"Ah, the Grail... Come, I will take you across. And afterward, dine with me at my castle."

Percival accepted. The old man carried him over the river and invited him to the castle — which, to Percival's surprise, was the very one he had seen from the bank.

"Who are you, sir?" Percival asked in wonder.

"I am the Fisher King, guardian of the Castle of the Grail," the old man replied.

The Fisher King was very old and carried a wound that never healed. He could only fish while sitting down, and that is why he was called the Fisher King. His whole kingdom suffered with him: the lands were barren, and nothing grew. It was said that only the knight who found the Grail could heal him.

That night, Percival dined at the castle. The hall was magnificent but sorrowful, and silent servants brought in the food. Then something extraordinary happened.

A procession entered the hall. First came a youth carrying a lance that bled — but the blood ran up the lance instead of down. Then came a maiden with a silver platter. And last of all, another maiden carrying a chalice covered with a white cloth. It was the Holy Grail.

Percival felt his heart pounding. He wanted to ask about the lance, about the Grail, about the king's wound. But he remembered the lessons in courtesy he had learned: a knight should not ask too many questions. So Percival kept silent and asked nothing.

The procession passed by and disappeared into another room. The meal went on, and Percival went to bed.

The next morning, Percival woke to find the castle empty. Completely empty: no servants, no Fisher King, no one at all. Confused and frightened, he mounted his horse and rode out. The moment he passed through the gates, they slammed shut behind him.

A voice cried from the walls:

"Foolish knight! You saw the Grail and did not ask! If you had asked the right question, the Fisher King would have been healed and the kingdom restored. Now the Grail is lost once more."

Percival was heartbroken. By being too polite, by asking no questions, he had lost his chance to find the Grail and heal the Fisher King. He wept bitterly and made a new vow:

"I will seek the Grail again. I will not rest until I find it. And this time, I will ask the right questions."

Percival continued his quest for years. He faced terrible temptations, when demons disguised as beautiful women tried to lead him off the path. Wicked knights tried to kill him. He endured cold, hunger, and loneliness. But he never gave up: his faith kept him strong, he prayed every night, he helped everyone he met, and he fought only in just causes.

One day, he came upon a hermit living in a cave — a holy and wise man.

"My son," said the hermit, "you seek the Grail with a pure heart, and that is good. But the Grail is not only a chalice. It is a sign of God's grace, of divine love. Only those with faith and a pure heart can see it."

"I failed once," Percival confessed. "I saw the Grail, but I did not ask the right questions."

"Then you have learned," the hermit smiled. "Compassion matters more than courtesy, and asking with love is better than polite silence. Keep seeking, Percival. You are on the right path."

Percival rode on, wiser and more determined. He knew now that seeking the Grail was not merely hunting for an enchanted cup: it meant becoming better, purer, more compassionate. Other adventures awaited him. He fought the terrible Black Knight on a haunted island, saved a queen from an enchanted castle, and defeated a dragon that frightened a village. With every adventure, his faith grew stronger and his heart grew purer.

But the Grail still slipped away from him. Where was it? Who would find it? The answer would come, but not through Percival. For there was another knight, purer still, destined to find the Holy Grail. That, though, is the second part of the story.
