The Saruthi are a minor alien race.
Biology and Culture
They have no optical or auditory organs, but sense the world with a sensory combination of smell and taste that are extremely well developed by human standards[1b]. An interesting feature of their society is their reliance on bending reality with the use of four-dimensional space, which gives the Saruthi and the landscapes of their worlds (called "tetrascapes") a lack of symmetry that is unnerving to anyone that views it, as well as creating their method of interplanetary travel. Instead of relying on space travel, the Saruthi utilized four-dimensional "tunnels" for interplanetary travel, not unlike the Eldar Webway.[1c]
They are described as being somewhat arachnoid or crustacean, with five limbs forming off of a flat, gray body in no particular symmetry. Their head was oblate and supported by a thick, boneless neck from the middle of their body. They are around two meters tall and weigh twice the mass of a man. They walk on silver stilts, adding a further meter to their height[1a]. In addition, their blood is a grey ichor, and they have the ability to form a field of electric-blue energy around their head which can offensively fire bolts of energy.[1b]
There was also another form of Saruthi which were utilized as slaves. They were sickly, bloated and misshapen, and had wrinkled, white, blotchy skin and a restraining device attached to their legs instead of stilts.[1a]
The saruthi had an ancient and small empire of about forty worlds, until human refugees offered them the Necroteuch, a chaotic tome. The knowledge contained within corrupted them utterly. The knowledge entered into their souls and minds, even their genetic code. A civil war engulfed their empire, leading to abandonment of many outposts and colonies. Their empire shrank immensely.[1b]
One old world of theirs that had been abandoned as a result of their civil war was designated in imperial records as KCX-1288. Another world which held a surviving population of Saruthi was the world known as 56-Izar[1c], which had been invaded by several human forces searching for the Saruthi version of the Necroteuch. 56-Izar was subjected to Exterminatus after the Saruthi Necroteuch was destroyed. No contact was made with the Saruthi again.[1d]
