One through four are allied, and start building something resembling civilization. All four pass completely over the one object which could have explained the mysteries of their universe, dismissing it as a mere child's toy that is fun to use on moving level changers. Psi abilities are finally achieved, causing major conflicts. Note, these species are much too argumentative and primitive. This does not grade well.
Culture continues to develop, but true peace and knowledge is never achieved.
Part of this problem is the lack of comprehension regarding the 'toy' mentioned earlier. That alone might have saved the project. Species three, despite being the original binding force, breaks the bind and all four are thrown into heavy war. They are all killed by various primitive weapons which can only remove three star systems at once. Six continues on, halfway to normal civilization, and five continues to cramp the space they are given, as most of reality two was destroyed along with reality one.
