Bonds of Aethelgard: the Twilight (Vol. 25)

Summary

In an underground labyrinth where time flows backward, a young blacksmith who inherited a sword that burns with white fire discovers a series of red signal fires lit along the deserted cliffs that could summon a celestial leviathan that lives within the deep ocean. Pursued by a mechanical colossus awakened from its centuries-long sleep, they must race against time before the last petal of the golden lotus drops into the basin.
