The Astraios Star System is located some 75,000 LY spinward of Pinastri, deep in the Gamma Quadrant, beyond the Tamlaa Vortex in a region of space unexplored by the Federation. Here three small planets orbit a relatively young star. The huge asteroid belt at the edge of the neighbouring Treman system stretches into this region. The innermost planet, Astraios, is an M-class planet. The humanoid population is primarily settled on the northern continent, where fresh water is easily available for crop growth and consumption.
