While examining a mysterious substance, Rackam runs into an old friend who leads them to the capital city of Mizarea.

The Auguste Isles are taking fire from the Erste Empire's attack. Gran pursues the abducted Lyria, rushing towards the airship landing site, where the empire's warships have appeared.

Gran and company visit the Lumacie Isles to wake up the comatose Lyria. Rosetta leads them to a giant tree nestled deep in a forest and summons Yggdrasil, the primal beast that protects Lumacie, and explains how Gran can enter Lyria's consciousness.

Lyria returns with Gran and the others to Auguste. Eugen is on the verge of giving up, and the skilled knights work to protect Auguste.

Djeeta is a girl who lives on the remote island of Zinkenstill. After meeting Lyria, they leave on a journey into the sky, as if guided by destiny.

Leaving behind his homeland, Zinkenstill, Gran continues his journey with the other skyfaring crew members, hoping to reach the Island of the Astrals.

Gran and the others are on the run from the Erste Empire, when out of the blue, the Empire proposes peace talks, and the crew heads to the Albion Citadel for the negotiations.

Gran and his crew are acquitted, thanks to the Erste Empire's pardon. But the morning after the banquet, they wake up to find Katalina gone, having left behind only a letter.

Due to a past incident, Katalina feels indebted to Vira and wants to provide her support after the many years of pressure and loneliness Vira has endured as Lord Commander.

Releasing the primal beast Luminiera's power, Vira attacks Gran and the others. When she sees Vira in berserk mode, Katalina is consumed with guilt. And so she makes up her mind to face up to Vira's feelings, to make up for the past.

After leaving Albion, the Grandcypher lands on an island shrouded in thick mist, notorious for being inescapable.
