One thing is certain about Implausiba: you wont get a suntan you like.
with its tiny sun bathing its vast, ponderous planet in massive amounts of radiation to heat it, the 26 billion on it's surface live in near-darkness, At once quelled into submission by the crushing weight of the massive gravity, and the ever-present weight of the Arbites, whose law in the name of His Most Geriatric Bitumen Hoarfrost, Planetary Governor intrudes into every single one of the low, squat hives that peek out above the incessant mangrove swamps
The governor, now aged a venerable eight hundred years old, benefits from his off-world palaces, on the largest of the planets innumerable moons, which wrack the planet with earthquakes.
In such a dismal, oppressive, unlit place, it is perhaps no surprise that Imperial force recruitment is almost unable to cope with the demand for places. As a result, from the widespread militias in the hives, under the constant watch of Arbites officers, people exercise and drill to be accepted into a massive military complex taking almost 1/4 of the planet's surface, which processes a quarter of a billion recruits every year.
With a punishing training regime which sees a large percentage fail to pass through basic training, the Imperial guard churns out many of the best trained soldiers, pilots, and supporting personell in the sector, benefiting from its exceptional standard of equipment through footsoldiers and navy, and respectable armoured units and titan legions.
