The Watcher of Aethelgard: the Ocean (Vol. 140)

Summary

In a forgotten archive deep beneath the city library, a disgraced knight seeking redemption in the borderlands discovers a silver cylinder containing the memories of a fallen emperor that could shatter the fragile peace treaty between warring kingdoms. Pursued by the Ash King, an ancient warlord entombed beneath the bedrock, they must race against time before the military vanguard crosses the river border.
