Echoes from Deepwood: the Red Signal (Vol. 126)

Summary

In a high-altitude fortress carved from solid mountain ice, a street-smart thief searching for a legendary key discovers a copper coin that never falls on the same side twice that could summon a celestial leviathan that lives within the deep ocean. Pursued by the shadow syndicate known as the Obsidian Hand, they must race against time before the military vanguard crosses the river border.
