Shelter Syem

Shelter Syem was based off of the New York City shelter's design. It was able to house the sum of twenty million people of Russia's and Ukrain's population. It is the largest of the three shelters in Russia, as the three others only held under a hundred thousand. This shelter however was the site of human augmentation, where most of the individuals underwent modifications at a genetic level to improve their chances of survival.

Human Augments
A majority of augmented humans within the Syem Shelter were known to have the ability to get nutrients from Compact Fluorescent Lighting which is used to emulate sunlight in order to cut down on rations. In a way, it was a form of photosynthesis. They were also capable of absorbing energy from moonlight emulated lighting. These modifications were also thought to be good for when they were to re-emerge on the surface, as the modifications would also work with natural light sources as well.

Humans of Syem Shelter also gained other augmentations which were generally used to create classes and occupations. These classes would stem from precursors and so on and so forth. Several generations would have several different things to choose from when it came to choosing an occupation. Such as scientists and engineers having enhanced capabilities relating to the mind. Mechanics and laborers with their physical conditions. As generations began to be born within the walls of Syem, these classes became wide spread. The child of a scientist and engineer, could succeed in feats where their parents couldn't, since there was no selective control via from the Government(s) which had collapsed on the surface.

Reemergence
When Syem's doors finally opened on the surface after first contact with humans across the globe, they found themselves in a lost world. Nature took over the world in their absence, be it for the better or for the worst. The Nuclear power plant was found to be in a meltdown phase with no one maintaining it and they were forced to flood the facility as well as Shelter Stem. However, they didn't lose a single person from their shelter after they emerged. Instead they used their resources and demolished the old buildings and began to settle a city several kilometers away from Shelter Syem's location. It is simply known as City Syem, or City Seven in English.
