Hollowwing Bat — VESSELBORN Codex

Hollowwing Bat

Noctivagus Kelanis

Origin: Kela (polar shelves, cliffs)

Length: 1.0 to 2.5 meters

Weight: 60 to 400 kg

Lifespan: 30 to 50 years

The Hollowwing Bat is a giant nocturnal predator of Kela's polar shelves and cliffs, ranging from 1.0 to 2.5 meters and 60 to 400 kg. Its reptile-like skin is covered in small hairs that shield against cold while a soft underbelly stays exposed. Very large eyes and protruding ears wrapping from forehead to back of head enable echolocation for silent swoops through the dark.

The Hollowwing Bat actively seeks humans, especially pregnant women, adding nothing to the ecosystem and disrupting the recovering gender ratio that the planet cannot afford to lose further ground on. This has prompted dedicated hunting groups in Kela to pursue its eradication. The Kela Maritime Guild pays for each body as proof of kill, offering the poor a path out of poverty through the hunt. It is one of the few species on Geba whose extinction is actively pursued rather than prevented.

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 people of the mountain passes lose their ancestral name and are permanently renamed 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. Assassinations and civil wars follow — the Fracture — but the answer is not a vacuum. The Shadow Rule forms from imperial networks and manufactures peace, ending the warlord broadcasts and taking the world back from collapse. They are the empire made quiet: continuity without ceremony.

Today, the Shadow Rulers still govern from the background while the Energy Wars — covert struggles over power grids and relays in uncivilized regions — decide who controls energy, transport, and culture.

Stories range from relay-field defenses and inland recoveries to city governance and frontier resettlement; from rail lines and air programs that stitch regions together to festivals and work crews where culture and politics collide; from Frost Sentinel memory 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.
