This high-speed airship measures 42 arge in length, and is the pride and joy of the Zeiss Central Factory. The Arseille can reach a top speed of eighty-nine arge per second (a later upgrade to its specifications allowed it to cruise at one hundred arge per second).
In Trails in the Sky SC, Finale: "Trails in the Sky", the Arseille manages to escape the Glorious' pursuit and bombardment but before closing in on Liber Ark, Leonhardt appeared riding Reverie Dragion and shred away Arseille's auxilary engine, sending Arseille crashing down into the floating ancient city.
Development on the Arseille started in S.1199 and construction took three years. In S.1202, ZCF started commencing test flights.
