It's been
four years since Reiner and Bertholt's second attack on Wall Rose (battle of Trost, etc). So three years after the chapter where we last saw Eren and crew (when they saw the ocean for the first time), which was a year after Trost.
This was stated in the last chapter, but it was confirmed this month when it's stated that the initial attack by the Colossus and Armored Titans (when Eren lost his mom) was "9 years ago".
Eren should be around 19 years old at this point.
Cool things:
Mickasa and Levi are confirmed superhuman warriors
Marcel who was eaten by Ymir is the brother of Galliard
That weird titan who walks around on all fours and carries **** is a woman lol
Zeke and Reiner will soon die
Zeke alone can control Eldians injected with his spinal fluid because of his royal bloodline
Eren and Armin have become incredibly powerful and it is even possible that Eldia has taken control of Annie's Female Titan. Eren may even have complete control of the "Coordinate" by this point.
Zeke may not be just a complete genocidal psycho and may have his reasons for wanting what he wants.
YMIR MAY BE DEAD. I think the implication is that Galliard ate her.
Being a Titan warrior for Marley is really NOT a good look; it's a product of coercion and forced patriotism. Also speaking out against it will have your rights taken away and your whole family killed.
There are dimensions to the Marleyan political system that make this manga that much more GOAT status. There could have been an entire manga written from the perspective of these Titan shifter warriors.
IT'S ABOUT TO GET REAL
