Immigrants

The few that survived World War 3 have no interest in a life within the nuclear wastelands. As soon as reports of a safe haven in Lagos spread, the 'pilgrimages' to Africa became most survivors' life goal.

Though most seek refugee status and shelter in Lagos, not all do. Some prefer to remain in the nuclear wasteland and be a part of the 'new world order' supposedly established by mutant survivors. Some even make money off of helping others survive the pilgrimage or forging documents or even training them in certain forms of labour:

You see, Lagos is severely overpopulated, yet still in need for new immigrants to possibly change the tides of the war with the inama. Naturally, they do not accept any immigrant. In fact, they do not accept most. Only those skilled at desired labors are accepted and the most sought after are those, that can advance Lagos' dome, technology & AI: Engineers, physicists, skilled laborers doctors and military personnel. Also prioritized are those that bring valuable goods with them: AI remains, mechas, weapons... anything that can possibly contribute to Lagos' survival and expansion.

Amongst those that are deemed worthy, there is a ranking system, reflecting their worth and resulting in better or worse quality of life circumstances. Some immigrants may rise quite high, others may be doomed to live in the slums all their life -- which, most agree, is still better than the nuclear wastelands.

Those that are refused usually don't go down without a fight and, as a rite of passage of sorts, newly accepted immigrants are commonly enlisted as the 'Harbor Force': Tasked to screen new arrivals and, if necessary, eliminate all troublemakers at Lagos' borders.

Life of immigrants in Lagos
Life in Lagos is not necessarily enjoyable for immigrants. As the former colonizers of African nations, they are not popular, particularly not now that they are taking up valuable space & resources, finding shelter in a continet they once subjugated and left for dead. There is no love lost between many Africans and immigrants and, particularly, the AFA is quite extremist in their view of immigrants.

Still, even amongst themselves, immigrants are far from harmonic. There is a lot of strife, simply stemming from the fact that, not long ago, those immigrants fought each other during World War 3.

Most immigrants live in the harbor district, the poorest of all districts in Lagos. Only those that excel at a certain skillset may be allowed in the higher districts.
