Item from Attack on Titan by Hajime Isayama
The nexus point in the Paths where the Founding Titan accesses the power to control all Subjects of Ymir. Where Ymir Fritz has been building Titans from sand for two thousand years.
The Coordinate is the heart of the Paths — a luminous tree in a desert that exists outside of time, where the will of the Founding Titan becomes reality. It is here that Ymir Fritz, the first Titan, has spent two millennia sculpting Titan bodies from sand, one grain at a time, obeying the commands of every Founding Titan inheritor because she was never free enough to stop. The Coordinate is not a place so much as a function — the point where one mind can touch millions. When the Founding Titan reaches the Coordinate, they can rewrite Eldian biology, alter memories across an entire population, give commands to every Pure Titan alive, and — as Eren proved — awaken the wall Titans to begin the Rumbling. The power is absolute. The cost is absolute. Whoever touches the Coordinate holds the fate of an entire race in their hands, and the sand keeps falling regardless of what they choose.
Also known as: the Coordinate, the nexus, the tree in the Paths
