When the horn of Boromir's death sank under the turbulent waves of the Anduin River, it represented not only the fall of a general of Gondor, but also the morale and glory of a kingdom on the verge of being shattered. Only the shipwreck craftsman He Gu, the riverkeeper who mastered the secret technique of communicating with the ancient giant catfish, glimpsed the last glimmer of hope hidden deep in the filthy bottom of the river. He steers huge schools of fish, wrestles with shadow pursuers in shadowed waterways, and pulls at the wreckage of a warship carrying Boromir's broken horn. After going through hardships and dangers, he was finally dragged to the blood-soaked ruins of Osgilias, the former important town, and the hero's remains were revealed again. The horn was hung on the stone wall, and the tragic call tore through the battlefield - but the deadly poisonous darts fell like a sudden rain, and the century-old giant catfish school that had been loyal to the Lord suddenly withered in the turbid river water. Seeing the bones of his last companion being swallowed up by the water, River Bones swore an oath on the water of Anduin: His life and will will be with Gondor's final glory, flowing to the end of the bloodshed.
