In the ancient era when the Iranian Plateau had not yet been illuminated by city-states, the "Rose Star" in the night sky always shed a faint glow at midnight during midsummer. People said this was the tenderness scattered by the Star Envoy. At that time, the plateau was covered only with thorns and withered grass; only a small tribe deep in the Zagros Mountains barely survived on melted snow water. Lina, a young girl from the tribe, would always pray to the starry sky: "If there could be flowers that make the land bloom with tenderness, I would give everything I have."

One midnight, as Lina fetched water by the stream, she suddenly saw a beam of light from the Rose Star fall onto the water’s surface, condensing into a dewdrop that glistened with silver radiance. When she reached out to catch it, the dewdrop transformed into a Star Envoy draped in a light veil. The Envoy said softly, "If you want flowers to grow on this land, you must exchange them with 'three hearts'—the heart of the first ray of morning sunlight, the heart of pure melted snow water, and the heart of your sincerity towards your people."

Lina nodded immediately. Every dawn, she climbed to the mountain top, held a clay bowl towards the east, and caught the warm glow refracted by the first ray of sunlight. She also trekked along the steep icy slopes to collect melted snow water untouched by dust. At night, she stayed by the tribe’s bonfire, warming the elderly’s feet and telling stories to the children. Her palms gradually cracked from labor and cold, yet she always clutched the clay bowl holding sunlight and melted water tightly.

After forty-nine days, Lina brought the "three hearts" to the Star Envoy. The Envoy poured the sunlight and melted water into a stone trough, then infused their own starlight into it, chanting incantations softly. The liquid in the trough gradually turned into pink flower seeds. The Envoy said, "Plant these on the tribe’s land. Whenever the Rose Star shines, the flowers will bloom, and the dew on their petals can heal wounds and nourish the skin."

Lina scattered the flower seeds all around the tribe’s land. The following spring, roses burst forth from the earth everywhere—their petals as smooth as silk, their fragrance drifting across the mountains. The tribespeople applied the rose dew to their chapped skin, and their wounds gradually healed; children dotted their cheeks with fingers dipped in the dew, and their skin became increasingly delicate.

However, the Star Envoy, having exhausted all their starlight, transformed into the most vibrant rose. When Lina hugged the rose and wept, a dewdrop from its petal fell into her palm, reflecting the Star Envoy’s figure: "I was originally a star guarding the tenderness of the mortal world. Now that I have become a flower, I will stay with this land forever."

Later, the tribespeople brought the roses to all parts of Iran, and roses have grown and thrived on this land for generations. People say that every petal of an Iranian rose holds Lina’s sincerity and the Star Envoy’s tenderness; every drop of rose dew is a covenant of "exchanging sincerity for beauty, and passing love through fragrance." To this day, when Iranians collect rose dew, they still whisper prayers to the Rose Star, commemorating the young girl and the Star Envoy who traded sincerity for a world filled with fragrance.
