I've spoken to Kim, and here's her thoughts:
Well, as AuroraDash made Jarodimia, I will let Michelle work on a continent of Olderth or Miderth (whichever one has a free space); Olderth and Miderth being two other planets that were discovered, in-universe, shortly after the birth of Selena Daria van der Merwe's child.
I will, however, still ask someone who has not worked on a Newerth continent and is a Beta Tester, if they would like to help with Elrochin. I will also have to check the Jarodimia thread; I suppose it's in the format of the other continents' threads?
(She's currently trying to cheer Charlotte up, not that it seems to help, though given what happened, can you blame Charlotte?)
