Saethera Skypillar — VESSELBORN Codex

Saethera Skypillar

Arboraltus saethera

Origin: Saethera’s warmlight forests

Record: Geban field flora

The Saethera Skypillar is an immense, fungal-linked tree species native to Saethera’s warmlight forests. Unlike typical arboreal life, its growth never halts. It expands indefinitely upward and outward, continuously merging with networks of fungus that circulate nutrients through its colossal trunk. The oldest known Skypillars, first recorded over three thousand years ago, still stand and continue to grow, their crowns lost above the canopy and their roots deep beyond reach.

Mosses, lichens, and parasitic vines thrive upon its surface, creating entire vertical ecosystems that stretch for kilometers. The Skypillar serves as both structure and sustenance, acting as living soil to countless smaller species. It is widely considered immortal, with no natural mechanism of decay ever observed.

Its fungal core and limitless growth make it one of Geba’s most extraordinary living phenomena. Less a tree, and more a perpetual biosystem towering across epochs.

About Vesselborn

Vesselborn is the story of Geba, a world that has carried an empire for six thousand years.

It begins with Vaer'karesh, who unites five nations into the first empire and fixes a common language and law. Across the ages, the empire fights and finally breaks Thazvaar, welcomes Jeyrha through engineering and diplomacy, and liberates Berinu by choice. In Ngorrhal, the greatest warriors of the mountain passes become the Frost Sentinels, whose strength helps secure imperial rule. The Haavu cannon systems cement that dominance.

At its height, the empire spans continents and raises relay towers that bind cities, coasts, and passes into one network. The last emperor is assassinated and the throne shatters. Civil wars consume the planet. But the answer is not collapse. The Shadow Rule forms from what the empire left behind, ends the warlord broadcasts, and holds the world together without a crown. They are the empire made quiet: continuity without ceremony.

Today, the Shadow Rulers still govern from the background while the Energy Wars decide who controls grids, relays, vehicles, and culture. Nine faiths compete for how the world understands itself. Tour racing draws audiences as large as the Yuvaar Hunting Games. Relaymen carry broadcast rigs into corridors and criminal networks to capture what the governed world is never meant to see. Contractors move through contested territory for manufactory interests. Syndicates operate trafficking networks through grey zones the empire tolerates rather than confronts. The Engineered, once created as instruments of war, now live as citizens, athletes, engineers, and parents.

Stories range from relay field defenses and inland recoveries to city governance and frontier resettlement; from airship crews racing through volcanic caverns to truth seekers embedding in syndicate operations; from arena fighters practicing an ancient faith through combat to families choosing the safety of hub clearings or the risk beyond the grid.

This is Geba.
It began in silence.
It has not yet ended.
