I've cleared Ceizak and Marjami. I believe I need to clear Morimar and Foret in order to get the KI to enter Yorcia and Kamihr.
I will still farm for a KI pop.
I'm at the point now where I'll gladly pay for clears. I've got 500k plasm just for 3 clears during this campaign. That would not be many to reach 2.5M.
