Attack On Titan: The Source Of All Living Matter, Explained

The progenitor of all Titans, speculated to be origin of all life on Earth, the “source of all living matter” is an organic anomaly which gave Ymir Fritz the Power of the Titans when she first encountered it nearly 2,000 years before the start of Attack on Titan. An entity whose true characteristics and qualities are still quite unclear, the organism was quite symbiotic in its existence, constantly looking for other hosts it could bond with. By fusing with other organic-life-forms, the entity was able to dramatically alter their characteristics, as seen in how the tree it originally resided within grew to a massive size when compared to neighboring vegetation in its vicinity. In addition to being the root of the Power of the Titans, it is also the source of the Founding Titan’s power, such that it binds intself to the spine of each holder of this particular Titan. Ymir first encountered the anomaly while being pursued by the soldiers of King Fritz, when she was condemned to death for opening the gate to a pen which released a group of pigs belonging to the Eldian tribe. After stumbling into a massive tree in her wounded state, Ymir fell into a pool of liquid inside the trunk which contained the entity. On noticing Ymir, the organism reached out and bound itself to her spine, turning her into th first Founding Titan.
