Part of the Mu Herculis ternary system. Mandra Quin'Si had largely lost its atmosphere and was slowly heating up as Mu Herculis A grows brighter.

K4H and TakiCorb partially terraformed this dry planet, covering the desert surface with wide canals fringed by irrigated land. Mandra Quin'Si resembles the classic atomic age pulp sf fables of Mars, although in this case the canals and decadent cities were built by human slaves ruled by the tyrants known as the Terrorlords of the Quasa'an Dynasty.

In 2446 the Tsutari Ambastory, a religious confederation drawn from the habitats across the system, overthrew the Quasa'an dynasty, bringing the era of tyranny to an end.
