Inexperience would settle in first, those ranging from the 35 point on the ki list down would immediately form alliances between themselves and others as they most likely won't know many of those whom they have found themselves with. Naturally, those being of older age and well knowing of those they were working with would create a system of trust between each other as years or so of Rping and OOC chatting has developed a form of bonding amongst the minority. Those ranging from 15 through 35 would have had connections with each other, as they had been a slightly newer addition to the Chubbs family around two or so years worth, thus giving a more of a sophomore-junior feeling as they could be represented as the "middle child" of the Chubbs community.
Gradually a dull sense of stability would come about as each of the three groups (we'll call them tribes for the time being) coexist for the moment, each stemming from what they learned in real life before this drastic change of events had occurred. Things such as food and water would be found by the elders as that would come first to mind, finding sources to survive upon. Thus following along would be the juniors tribe then the younglings.
Soon mistrust will follow along, people realizing more and more each day that this has become their new homes. Some turning against each other as small things such as food begin to dwindle away, inner alliances within the tribes begin to form and solidify as the type "A" people (ones who excel at leadership skills) start to branch out to other sectors of tribes. Most likely this will occur in the junior sections, turning to the younglings as a source of recruitment after learning that they need connections with a higher force. Especially if the newer people are of type "B" decent of person.
Heated conflicts begin as those remaining to their common sense within the junior tribe become closer to the seniors, knowing full well the capabilities they hold as well as the beneficial factors of the alliance. Now split into two separate groups versus the initial three that began, those in league with the small consent of peoples higher in the ranking begin realizing quickly the demands this combination of junior and freshmen are making are insane. Obviously a lust of power on the minds of the combo tribe (tribe B from here on) are driving the leaders as their destination is set for exceeding those of the higher ones (tribe A).
Now at a full out war between each other, the older ones in tribe A show their authority by skills presented to them in their life. Military, training, any thing of physical value coming into course of action. Unfortunately there hasn't been any way of keeping frame of body, muscles now reduced to a fragment of what they had been in both tribes. Finally out of sheer numbers, tribe B reduces tribe A to a shell of their former selves. Weakened by nights and days of fighting, food has become a danger as those fighting haven't had the energy nor time to venture out for a decent piece of meat or fruit. After what seems like weeks tribe A is vanquished while tribe B is reduced to a pathetic attempt to forage food for themselves as many roam injured, those not fighting being too young of age to harvest it themselves. Eventually leading to the starvation and finally the death of every single member of Chubbs...
