The First Layer

The ruins seem to be centuries, if not millennia, old. At first it seems to be only a large open-air dome, but as we are excavating the outermost parts we quickly find ourselves in what appears to be the derelict slums of a city. As a large gate blocks our progress deeper into the city, our scientists speculate that it is split into a hierarchy, each layer holding one class of the people of the city. It does not take long before one of our scientists finds alien remains in subterranean ruins under the broken concrete floor. After the first corpse is found, however, we start finding remains all over the slums, be it in the streets, in what would have been their homes, or hanging from the most remote parts of the ceiling. It is unclear what killed them, but it is a grisly sight.
