HD-51 1306 A III.9, or Sheba's World to its Martian-Tweak inhabitants is an earth-like world with a Young Incompatible Biosphere and an unbreathable atmosphere of mostly carbon-dioxide with volcanic taints of silicon and sulfur dioxides. There is no land-based animal life to speak of, though the seas are teeming with all manner of weird creatures. The Tweaks who make Sheba's World their home have an efficient system of pulling useful amounts of oxygen from the atmospere while rejecting the CO2 and the volcanic taints. While they must wear specially tuned respirators to leave the shelter of their habitats, they have managed to efficiently explore several thousand hectares of land around their primary habitat cluster, and have set about cataloguing and examining the flora for usefulness to the colony.
One of the hazards of living on Sheba's World, aside from an atmosphere unbreathable by unmodified humans, is the moon's interactions with the intense magnetic field of the parent gas giant. Radiation levels are significantly higher on the surface of the world, which may account for the lack of land-based life forms. Unshielded organisms on the surface of the planet receive a dose of roughly 0.5 millirem per hour.

Neu Baeyer was settled in 2358 by a German commune of ascetics looking for a harsh and isolated world to test their devotion to personal and group meditation and to their communal way of life. The colony lives underground in sealed domes and maintains a subsistence agricultural base that satisfies their strict vegetarianism. They have been likened to a monastery populated by atheists, and have drawn the occasional convert looking for spiritual guidance.
