Fthos

Fthos—called "Quator" on Arbre—is one of the four origin worlds associated with the visiting Geometers. On Arbre, this origin has been informally labeled the Quators, after an icon that appears to depict a world whose landmasses lie mostly at low latitudes.

The name “Fthos” entered local discourse when a Laterran envoy disclosed internal alignments among the four visiting peoples during protected discussion at Tredegarh. In that account, Urnud and Tro form an alliance known as the Pedestal and are hostile toward Fthos; Laterre is divided in its loyalties. Subsequent briefings add that the shipboard opposition movement, the Fulcrum, is led by Fthosians.

According to the same source, life aboard the Daban Urnud includes families and schooling, with children of Urnud, Tro, Laterre, and Fthos raised to compete for positions in the ship’s Command. Fthosians are one of the four communities represented within the Orbstack.

Fthos is recognized within the four‑world presence orbiting Arbre. Beyond the political alignments reported above, no confirmed details about Fthos’s geography, culture, or governance have been presented.
