Updated all logs, may re-write in some cases, but the gist and essence of that particular race is there.
I also included the fourth race, in case you hadn't already guessed though most of you know, they are an advanced race of cybernetic beings, they have been around even longer than the insectoid species, no human or machine has seen one, though the Insectoid race had a massive war with them several centuries ago and barely managed to survive the extermination (yes I get the "If they are so advanced why didn't they manage to exterminate them entirley?" question) I suppose the answer is that the Insectiod race is huge, several hive could have been in hibernation, regarless this fourth race, though very powerful is not infallible.
Can't decide whether to add this race as a playable race, or turn them into the Pirates? I am not much of a modeller etc so if I did turn them into a playable race they would look pretty much like the Advent, just with different effects, research etc
If they aren't the pirates, I am not sure what could be as I was thinking these advanced cybernetic beings could be what the Vasari were running from, (Sentience being my take on the Sins world).
