==Home World==
Mare Aeternam is a small cold hive world almost fully covered with water. Inhabitants try to overcome the lack of ground under their feet and intolerable frost by hiding in tremendously high tower-cities and floating settlements. This paradoxical mixture of liquid water and extremely low temperatures (which rarely rises higher than 20 degree below zero) is explained by the abnormal  saltiness of the local oceans. The amount of fossil fuels is too insignificant to discuss; in order to maintain life in the megalopolises, solar and wind power plants are used, which are unbelievably effective in planetary conditions of constant wind and a thin and almost nonexistent ozone layer. Hives even have quite specific mushroom-like shapes that provide the best placement for the power plants. The planet is uninhabited except for humans and Terran bacteria which were brought by the first colonists as the source of food and oxygen.

Such severe conditions force the inhabitants to be maximally cruel and pragmatic; constant lack of space and overcrowding lead to a merciless, Spartan system where sick and useless citizens are forcibly euthanized. Family institutions are replaced by a government system which monitors every step of a child's development and eliminates every unworthy in order to make the best, most loyal specialists ever. It's a brutal but effective solution for problems which usually plague hive worlds: the genetic health, productivity and viability of the nation improve every generation; there are no declassified groups and as a result no place for chaos/genestealer cults to get a foothold (we think); and the military system has very little stagnation as aging officers are regularly replaced.

Furthermore the level of crime in the cities is also extremely low due to constant surveillance both on the streets and in residences. Despite these grim conditions the residents are happy to live here; constant propaganda since birth means they tend not to consider other forms of governance.
