Many had died on that part of their journey. Small injuries that would have healed quickly in the caressing salt water of the sea became festering ulcers in the river’s harsh flow. After their long banishment at sea, many of the great serpents were feeble both in mind and spirit. So many things were wrong. Too many years had passed since they had hatched. They should have made this journey decades ago, as healthy young serpents, and they should have migrated up the river in the warmth of summer, when their bodies were sleek with fat. Instead they came in the rains and misery of winter, thin and battered and speckled with barnacles, but mostly old, far older than any serpents had ever been before.

The single dragon that watched over them was less than a year’s turning out of her own cocoon. Tintaglia flew overhead, glinting silver whenever the winter sunlight broke through the clouds to touch her. “Not far!” she kept calling down to them. “Beyond the ladder the waters deepen again and you can once more swim freely. Keep moving.”

Some were simply too battered, too weary, too thin for such a journey. One big orange serpent died draped across the log wall of the penned water, unable to drag himself any farther. Sisarqua was close to him when his great wedge-shaped head dropped suddenly beneath the water. Impatiently, she waited for him to move on. Then his spiky mane of tendrils suddenly spasmed and released a final rush of toxins. They were faint and feeble, the last reflexive defences of his body, yet they clearly signalled to any serpents within range that he was dead. The smell and taste of them in the water summoned her to the feast.
