The Euclid 13 system exists at the extent of the Askellon’s trailing border. The system is rarely accessible, having been cut off by the Pandaemonium many times in history. All of the eight worlds in the system appear to be clones of one another, exhibiting nigh identical mass, dimensions and other gross characteristics. The only variation to be found is in the surface conditions, but most Mechanicum researchers believe these merely a reflection of each planet’s vicinity to the central star.
So far as the archives relate, only a single world in the Euclid 13 system has been visited. The third planet out from its star, Gamma Euclid 13 is reportedly a world dominated by distorted terrain formations that appear twisted out of shape as if by the whim of some mad god. Enormous spirals, arches, and limbs of rock tower far into the sky, seemingly unaffected by all normal laws of nature. It is not these strange formations that have earned the world a dire reputation, but that every expedition has fallen victim to some manner of guardian, only a handful of survivors returning to relate their terrible warnings of terrors emerging from the dark.
