There's something I've been wondering about; is it ever explained why the noble bloodlines of the walls are immune to the King's memory powers? Are they actually Marleylans, or some other non-Eldian group?
No. I don't think it was. I remember writing reams of meta back in the day about the different bloodlines and wondering what it all could mean but either we read too much into it or else it was a storyline dropped. Mikasa's Asian heritage resulted in nothing and the Ackerman power was introduced but never consistent or explained.
For those reading who don't know what this is about, the Eldian history that opened Volume 22 referred to the “Subjects of Ymir” as the race that could be controlled by the Coordinate and transformed into titans. In earlier portions of the manga, the nobles (Ch 63), the Ackermans and the East Sea Clan (Ch65) were presented as minority bloodlines (or clans) who are part of the Eldian Empire and yet free from the mental manipulation that plagued the "slave class". The disconnect is that in 126 both Levi and Mikasa were transported to Paths by Eren acting as the Founded Titan and in 138 Mikasa's memories were revealed to be influenced by him.
In the end, the only thing truly immune to the Founding Titan's power was Hange's wheel. Go figure.
Thanks for the ask!
