Because the Tower whispers secrets to those who stay: how to catch a falling star, how to weave time into rope, how to look at a storm and say kneel . Each level grants a new sense, a new weight. By the fifth floor, a girl can taste lies on the wind. By the sixth, she can remember tomorrow.

So they stay. They grow. They braid each other’s hair in the humming dark. They are not sisters by blood, but by the weight of a choice they remake every dawn.

But the seventh floor? No girl has ever described it. Those who ascend return with eyes like novas and a terrible, gentle smile. They take up their posts in silence. They watch the horizon.

Outside, the world grows old and forgets the Tower exists. Wars are fought. Songs are written about other things. But high above the clouds, the girls keep their vigil, because the Tower told them what sleeps beneath the earth—and what will wake when the last girl finally walks out that unlocked door.

A new name already taking its place.

Lin —already fading.

They arrive as girls. They become something else.
