Titan Biology Research Society

The is a Marleyan organization dedicated to the study of Eldian people and the true nature of the Titans.
== Duty ==
Established sometime after the Great Titan War, the Titan Society focuses on analyzing the nature of the Subjects of Ymir and their connections with the Titans and Titan power. Information gathered from the Titan Society is shared with members of the Marleyan military, though it appears that members of the Eldian population within Marley are not informed. It is unknown whether the common Marleyan population is given the information obtained by the Society.
== Findings ==
Sometime before the year 832, the Titan Society proposed a theory that centers around the Founding Titan: All Titans and Subjects of Ymir are connected to each other through invisible "paths" that transcend physical space, and these "paths" converge at a single coordinate; this so-called "Coordinate" is the Founding Titan.
In later years, the Titan Society also researched the strange case of Zeke Yeager, who could inexplicably control Titans created with his spinal fluid; however, no conclusive results were made concerning this phenomenon. The Titan Society is unaware that Zeke possesses royal blood, granting his Beast Titan powers similar to those of the Founding Titan itself.
Titan scientists, presumably affiliated with the organization, noted that family relations between inheritors of the Nine Titans play a significant role in passing down memories.
According to Eren Yeager, Marleyan scholars know very little about the Titans, with Zeke Yeager knowing more than them.
== Developments ==
Over multiple decades, the Titan Society was able to develop multiple objects and weapons linked to the Titan powers in order to help the Marleyan military's goals. 
The organization is responsible for all the serums made of Titan spinal fluid that have been created in Marley. Being a serum-based method of transforming Subjects of Ymir into Titans, the Marleyan authorities have used it countless times over the years in order to turn Eldian criminals and traitors into Titans in order to wander the non-Walled territories of Paradis Island, or attack enemy armies in imperialistic conflicts against different countries around the world. The serum has also been used by the military to pass down the Titan powers from Warrior to Warrior. The Society has made it so that the serums would make the size of the resulting Titans be controllable by any Marleyan soldier of officer that would want it.
In recent years, thanks to Zeke's unique power, even though he managed to conceal his royal blood from Marley, the Titan Society scholars have managed to work with Marleyan military in order to develop weapons coupled with his unique abilities that they could use against the country's enemies. His spinal fluid has been used in 844 to transform hundreds of Eldians who were sneaked into one of Marley's enemy nations' capital city, after having been administrated Zeke's spinal fluid. This method proved to be a cheap way of conquering enemy cities and countries, and Marley has used it multiple times due to its success. The Society has also developed gas weapons with Zeke's spinal fluid in it, which the Marleyan military used in order to transform into Titans the entire Eldian village of Ragako on Paradis Island.
