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.
