The Legend of Ironclad: the Oracle (Vol. 84)

Summary

In a windswept harbor town haunted by ancient shipwrecks, a disgraced knight seeking redemption in the borderlands discovers a glowing parchment containing maps of stars that do not exist that could disrupt the magical beacons guiding ships through the mist. Pursued by a rogue celestial navigator who seeks to burn the stars, they must race against time before the iron gates of the underworld swing open.
