before returning home, the survivors recover grisha's memoirs from the yeagers' basement. his writings state that human civilization is actually thriving and the people of the walls are members of the eldian race, whose common ancestor ymir fritz acquired the power of the titans, granting her progeny the unique potential to become titans and inherit nine titan powers. ymir's descendants dominated world history for centuries until 100 years prior to the series' beginning, when the 145th eldian king retreated to paradis island and established the three walls with the founding titan, threatening to retaliate with the titans comprising the walls should his peace be disturbed. the nation of marley conquered the remaining eldians, quarantining them in ghettos and passing the seven captured titan powers to indoctrinated eldian "warriors" for furthering marley's national interests. grisha, along with his wife, dina fritz (a member of the eldian royal family's branch), conspired with other eldian dissidents to acquire the founding titan before marley and free their people but was outed by his son zeke yeager, eren's half-brother and the future beast titan, and sentenced to life as a mindless titan wandering paradis. however, grisha was saved by his movement's informant, who entrusted his titan power and mission to grisha and sent him to infiltrate the walls and recover the founding titan. eren learns that despite his lack of royal ancestry, he may be able to use the founding titan's full "coordinate" power through physical contact with a titan of royal blood.
