Related: Lesser Smilohound · Greater Smilohound

The Sentinelhound is a canid guardian native to Geba, a close relative of the Lesser Smilohound bred specifically for bonding with humans. Standing 0.2 to 1.0 meters at the rear and weighing 20 to 110 kg, it possesses extreme intelligence and adaptability that allows it to mirror nearby humans' personalities, forming deep bonds that reflect the behaviors and emotions of its owner with uncanny precision. The adage "A Sentinelhound is a mirror. Remember that" underscores its most notable quality: it cannot be deceived, because it reflects what is actually there rather than what the person wishes to project.

This quality makes the Sentinelhound trusted globally for protective roles from companionship to military security, and it is particularly popular among Tactician-Class Engineered for coordination in operational settings. Bred since the Era of Early Dominion, it is ubiquitous in capitals, relay hubs, and outposts, suited to woodlands, plains, and urban perimeters while absent from volcanic or subsurface extremes unless accompanying humans into those environments. It matures quickly and reproduces in rhythms linked to the human households it bonds with.

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.
