In Awakening, the Geosphere assumes a new name, Vert (碧炎 Aoen, lit. Green Flame).
In all games but the DS remakes (in which it and the Starsphere's colours are switched), the Geosphere has been consistently coloured green. In the artwork portrayal of the Shield in Awakening, Vert's place on the Binding Shield is accompanied by the inscription "green frame orb mother earth," poorly transliterated text that is certainly intended to be "Green Flame Orb, Mother Earth."
In Shadow Dragon and the Blade of Light and its remakes, the Geosphere first appears in Chapter 19, where it is retrieved by Marth's army alongside the Starsphere in the Fane of Raman. After the War of Shadows concludes, custody of the Geosphere is ceded to Altea, and is kept within the treasury of Altea Castle.
The Geosphere resurfaces in Chapter 16 of Mystery of the Emblem and its remake. As Marth's army prepares to charge Altea Castle and reclaim control over it, Jagen reports that a suspicious-looking Thief has been sighted heading towards the north. Coming to the conclusion that the Thief has stolen the Geosphere, Marth's army successfully chases him down and thereafter recovers the sphere. Alongside its other sphere counterparts, the Geosphere is later slotted into its allotted alcove on the Binding Shield following Hardin's fall in Chapter 20. With the assembled Binding Shield on hand, Marth will charge towards the dominion of Medeus to rescue the four kidnapped princesses and put an end to the War of Heroes.
In Awakening, the Geosphere is observed to have taken on a new name, Vert, and is originally in the custody of Chon'sin. Vert is first mentioned in Chapter 16, where Say'ri reveals that it had been stolen by Valm. It is later recovered by Say'ri after Walhart is felled in Chapter 20, who entrusts it to Chrom. It is then fitted into its corresponding alcove on the Shield, alongside Argent, Gules and Azure. The Shield is later stolen by Validar at the end of Chapter 21, who telepathically manipulates Robin into wrenching it from Chrom and handing it to him. The entire set is later recovered following the events of Chapter 23.
