Harvest Moon

Slumber washes over us like a wave, and the Dreamer guides us to a rising cliff in Night, where a stump exposed to the sky hums and glows with power. There are twelve threads upon it, each glowing with a unique aura, surrounding a red skull weeping eternal tears. But we do not stay at that stump. Instead, we pan down, scanning the rocks, until we arrive at a cave at the base of the cliff, where Harvest makes her home...
Harvest's cave was small and modest, with few possessions unrelated to her work. Crystals hung from the ceiling, absorbing the light of the full moon, and spreading it throughout the cave. Harvest sat below one such crystal, hanging above a wooden spindle. Mother had made it for her, in an age long before this one...
She sang as she spun, a Song that the Haze dare not carry. And so her lips moved in silence, as she ran the thread through the spindle, and then undid her work, and ran it through again. With each pass, the thread took on a progressively brighter, orange-yellow light. It was the light of the harvest moon, the source of her namesake, and the greatest foothold of Day in Night.
It was like her, as Alistair was like her -- a creature of the slumbering dark, touched by sunlight -- and thus the task of creating his thread had fallen to her. For her contribution, she would fight no dragons, or summon Wild Hunts, or sacrifice deceivers.
Harvest would sing, and pull the sunlight reflected off the moon, and make a weapon capable of harming her own brother.
The Haze accelerated the vision, as Harvest weaved and unweaved, singing all the while. At the end, the thread was a strange mix, half umbral thread, half solid daylight. Harvest looked at her work glumly -- it was the best working she'd ever done, but she took no pride in it.
The vision zoomed away from the cave, and panned back to the rising cliff, where Harvest walked with the thread in hand. Her sisters followed, in various states of exhaustion and injury, ready to see their working complete. Harvest knelt before the circle, adjusting the skull's jaw, and placed the thread between its teeth. The eternal tears fell over it, dying the sunlight an eerie red, while leaving the black thread unstained. As it found its place, the binding wavered, nearly complete...
Harvest pushed her energy into the circle -- the last of her sisters to do so -- and the binding set.
The effect was immediate.
The daylight thread began to sizzle, steam erupting from the skull's mouth, as the daylight thread began to fight against the forces of Night. The barrier around Ezorod shimmered, but did not break. It would not, not until Alistair was defeated... But this would weaken him. It would pollute the Day sickness inside him, and make him vulnerable. And once he was vulnerable...
Mother would come for him.
The Daughters of Night wept as they poisoned their only brother, and the vision fades...
