So, based on the 1st installment of Chapter 13:
"When whole-cosmologists made extended observations through the Omphalos, they discovered that the majority of the worlds were in the form of Pangaea. The second largest group were Gondwana, followed by smaller groups in Nuna and Kenorland forms. The smallest groups were Gaea -- which is the form in which we six current live -- and Neopangaea. Through time, however, whole-cosmologists noticed that the number of observed worlds in the state of Neopangaea was growing dramatically -- and the number of all other forms, except Pangaea, was much reduced. "
Does "we current live" mean before 1814/1815 event or after? If before,
I guess that Neopangaea is purple on the graph and Pangaea is red. The "form in which we six current live" (Gaea) must be orange since orange and purple were the lowest on the graph at the start. Purple then eventually crosses most of the other lines beginning in 1813. Note that it doesn't cross red which appears to be still increasing slightly on the graph while the others (except purple) seem to be dropping ever so gradually (except orange which drops alot).
Also note that purple essentially disappears after the drop. It's overdrawn by another line, which which?
If "current live" means after 1814/1815 closer to present day, then green is the second lowest and is thus Gaea. So:
Red: Pangaea (I'm sure of this)
Purple: Neopangaea (I'm sure of this)
Orange: Gaea (is this the lowest on the graph now? per installment 2 of Ch. 13 - Gaea is near RCC)
Lt Blue (Aqua): ?
Royal Blue: ?
Green: Gaea possibly
I still can't find purple on the graph after the 1814/1815 collapse.
