The First Forged are like demigods here, and from what I understand, answer to Primus. At the moment they are not here in Haven, though. They rather not have us here, but since they do not have a way to return us nor a way to stop new refugees from arriving, they decided to protect us, thus the glyphs.

I have only spoken with only two of the First Forged personally. Liege Maximo and Megatronus.
