The Dome

The dome was originally built around Lagos in order to protect its residents -- the only remaining Africans -- from the deadly inama virus.

As of 2116, the dome is not just home to African refugees, but to refugees from all over the world and houses roughly 250 million people. The dome is more than just protection though: It is the center of life as humanity now knows it:

Via a funnel system, it absorbs, stores and uses sunlight to power the whole nation of Lagos. Any and all energy & power supply is provided by the dome. As such, the dome is a technological marvel, intricately built and constantly improved upon by the finest engineers, always at work at maximizing its effectiveness.

The expansion of the dome is a constant desire for humanity but it is strongly opposed by the inama. The dome poses a threat to the inama's way of life, as it funnels in solar energy and runs on it. Thus every inch of expansion would exponentially increase the amount of sun that is absorbed. Consequentially, the area surrounding the dome loses the sun's energy supply and the lands become barren; no plants, no wildlife. This is a problem, no, a matter of survival for the inama, as they sustain themselves on sun-light alone and also consider themselves one with nature and its guardians. More than that, as part of their DNA is plant-based, the inama truly feel for nature and are one with nature and more than just a spiritual way.

Any attempt at expanding the dome is met by heavy resistance from the inama, particularly by their northern tribes, led by Noire.
