In the world of "Attack on Titan," the Marleyans are a dominant ethnic group and the ruling power in the land beyond the Walls. They are distinct from the Eldians, who are the main group of people residing within the Walls.
The Marleyans hold political and military control over the Eldians and have subjected them to oppression and discrimination for many years. They view Eldians as a "subject race" and have imposed strict laws and policies to maintain their authority.
Historically, the Marleyans used the Eldians' ability to transform into Titans as a weapon to expand their empire. However, after the Eldian uprising, the Marleyans gained control over the Nine Titans, including the Founding Titan, and established their dominion.
The Marleyan military, known as the Marleyan Warriors, employs Eldians as warriors, often using the power of the Titans for their own purposes. Eldian children are often indoctrinated and trained to become Marleyan Warriors, serving the Marleyan government and carrying out their orders.
The relationship between the Marleyans and Eldians is complex and fraught with tension. While Marleyans hold power and authority, they also fear the potential rebellion and strength of the Eldians. This power dynamic shapes the narrative and explores themes of discrimination, oppression, and the abuse of power throughout the series.
The Marleyans are a significant faction in "Attack on Titan," and their actions and motivations contribute to the overall conflict and exploration of the world beyond the Walls.
