Truthuru are large and generally muscular aliens in the galaxy of Black Horizon. They are genetically related to the Surrians and they generally more closely resemble the original members of their race, who ventured into space and settled on distant planets.

Truthuru have six limbs, with four arms and two legs, but they predominantly use their massive forearms as legs most of the time. Their evolutionary homeworld has high gravity, and the additional support was needed for efficient movement. However, as they settled on lower gravity worlds, their posture changed, freeing up all their arms. This change in physiology led to the emergence of the new race of Surrians, while the Truthuru remained more or less the same.

Over thousands of years, this split between the Truthuru and Surrians has resulted in a racial war between the two, with the Surrians, in particular, looking down upon the Truthuru and calling them names like 'Wujisa jisa,' roughly translated to 'dirt hands,' referring to the Truthuru's continued use of their arms for movement.

However, the Truthuru see themselves as more closely connected to their original evolutionary heritage and homeworld, which gives them a certain sense of pride.

Truthuru remain incredibly strong and fierce, usually standing above 2 meters tall, but they can vary their posture to use only their legs for support, giving some a height of almost 3 meters.

There are roughly 6 billion Truthuru in the galaxy, but they are being vastly outcompeted by the Surrians, who often control vast stretches of space.
