Living Labyrinth

by Ian Stewart and Tim Poston

If you can't read St Matthew's Gospel because St Mark gave away the resurrection, don't explore further.

I like background on books:

Qish

The planet Qish is the third planet of a star (long neglected on Concordat star charts as Squill) slightly bluer and heavier than Sol, orbiting in the 'Goldilocks zone' at about 1.07AU, with orbital eccentricity 0.122. Squill's higher fraction of blue light may explain the evolutionary selection of a chlorophyll analogue that absorbs and uses the shorter wavelengths, while reflecting the red and green components that make Qishi vegetation appear yellow and orange to the human eye.

The solar year of Qish (the time it takes to circle Squill once) is 314.159265358793 times the length of its solar day, a fact in which only the Cave Dwellers of Wevory find mystical meaning, and comfortably compatible with human circadian rhythms. The Qishi sidereal day is longer by a few minutes, a fact which nobody on Qish has noticed or measured. The Qishi year lasts about 0.91 of a stanyear (which the Magog crash left the colonists unequipped to measure), or about 33 Old Earth days shorter.

The axial tilt of Qish is 21.7893°, which in combination with its orbital eccentricity of 0.18 causes some seasonal weather variation, though the Endless Ocean causes more smoothing out than in the continent-blocked climate of Old Earth. There is no polar land to anchor the formation of icecaps.
