The Coordinate

Lore & Background

Born from Ymir Fritz’s pact with the Source of All Living Matter, the Coordinate transcends physical transformation. It operates on a conceptual plane within Paths, allowing the user to rewrite genetic codes and memories across an entire race. For centuries, the Reiss family guarded this power through strict bloodline restrictions, using it to manipulate history behind the Walls. The barrier was not merely magical but rooted in Ymir’s own servitude; she remained dormant for two millennia until the convergence of Eren and Zeke Yeager allowed the restrictions to be bypassed. This revealed a capability far beyond command: the power to initiate global cataclysms, effectively turning the entire human race into a single, controllable entity.

In Their Own Story

The ground beneath shook not from footsteps, but from a collective inhalation. In the vast, bone-white expanse of the Paths, sand stretched endlessly toward a horizon that did not exist. Eren stood before the silent giant of Ymir, her eyes wide and unblinking, waiting for an order that had never been given in two thousand years. "Do it," he whispered, his voice echoing across the infinite void. "I am your will."

Suddenly, the silence shattered. A million voices spoke as one, a chorus of obedience rising from the dust. In the real world, millions of hardened warriors dropped their weapons, their eyes glazing over as an invisible command rewrote their very souls. The walls trembled, not from the impact of giants, but from the sheer weight of a single will overriding the free will of humanity.

Reader's Guide

Functioning as the spiritual broadcast network for all Subjects of Ymir, the Coordinate allows commands to bypass individual free will instantly across any distance. In practical terms, it enables mass memory alteration, control over Titan hardening, and the reshaping of biological structures within the Paths. While traditionally locked behind royal bloodlines, direct physical contact with a royal shifter temporarily grants non-royal Founding Titans access to this full spectrum of authority.

• The power extends beyond living humans, allowing control over Titan hardening and environmental reshaping.
