Invictus

Home to dextro-amino-based life, Invictus' temperate zones were settled by a turian population that initially fell prey to a bewildering number of diseases. Two decades after its first colony was founded, its population had reduced by half due to fatalities and a large colonist exodus. But when the Primarchs considered ceding the planet to robo-mining interests, the turian statesman Shastina Emperus ambitiously declared that she would start her own colony and double its population within five years.

The effort succeeded, largely due to the colonies' location in deserts with a minimal number of pest species. The image of Shastina's triumph in the frontier made for good political theater, and the turian population poured in. The planet's tropical belt still remains largely unexplored, as its aggressive organic life still wreaks havoc on turian biology. A "house in an Invictus jungle" is a modern turian phrase for an idea that seems like a good idea, but only to the one who came up with it.

Invictus' atmosphere is primarily nitrogen and oxygen, and its surface crust varies but has high concentrations of alumina and silver. Because it can support life easily, criminals from throughout the Terminus Systems hide out on Invictus. Its official population is estimated to be half the number of sapients that are actually on the planet.
