The Fourth Faction

The protagonist died, and regained consciousness in an unknown location. He kept some memories, and quickly realise he was reincarnated in an alien life form... A life form which wasn't unfamiliar. A life form full of potential. The protagonist also realise that there will be a lot of trouble in the future with the other races... Another "reincarnation in another world" story, but it's not a fantasy world. WARNING: Mature content of all kind once in a while, and more in later chapters
