Despite the star system’s ominous aura, the planet’s auspices are well-favored for human life. Beyond being blessed with liquid water and breathable air, the planet and its moon hold a sympathetic alignment with the toxic sister planet its satellites. Ill humors are drawn to the older sister’s vapor and leave the younger sister clean.
+++CLIMATE AND GEOGRAPHY+++
Jeroboam is recovering from a global ice age and is approximately 45% covered in receding glaciers. Nearly all planetary water is contained within these glaciers; the rest is locked inside inland seas. The largest of these seas is in the temperate equatorial zone and covers roughly 10 million square kilometers. Radio surveys suggest a large cave network adjacent to this sea.
Tectonic activity is low and there are few mountain ranges—more are suspected to be hidden beneath the ice sheets. The majority of the non-frozen surface is plains or tundra. Vegetation is concentrated along the shore of the equatorial sea.
The largest landmark visible from orbit is an impact crater several dozen kilometers wide at 30 degrees north latitude. The destruction of the impact was strong enough to trigger brief volcanic activity (now dormant) in a nearby mountain range.
The planet has a nickel-iron core but few surface deposits of valuable metals. Some sulphur mining may be possible in the volcanic regions.
The planet supports life, most notably a neolithic human or abhuman society. Flyover surveys indicate no permanent major settlements. Presumably these inhabitants are remnants of the ancient society listed in Administratum records, but there is little to say for their heritage.
Other prominent forms of native life include an immense but swift race of megatheric herd mammals, as well as webbed-winged ptera-beasts within the equatorial woods. The depths of the inland sea may hold life as well.
