I can not understand cephs. In Crysis 2 sad: these clams; buildings like a coral reef. Maybe it is not aliens, just the ancient inhabitants of the Earth, which moved away from the dream. So they are divided into subspecies: Lingshan cephs, New York cephs.

They were dormant because no suitable climate on the planet. But now it has become acceptable, so they come out of hibernation and decided to create the conditions for the further development of its civilization.

Why can't we be on ceph side? Why not? Prophet in game understand own language. Maybe cephs better than no so good humans.
