Birdman Empire

Lore & Background

The Birdman Empire is a separate race, not a faction within the Seiren. The Seiren are aquatic beings with fish-like lower bodies, lacking wings or inherent flight. They do not use magic to fly. Their society is based in the ocean, with no floating cities—those are inventions of the Avian race. The Seiren rely on naval and underwater capabilities, not airships. They were not initially hostile to humans; they are introduced in Volume 5, where Sora and Shiro challenge the Seiren leader Laila to a game and become allies after being defeated. They are not described as neutral observers or guardians of the airspace.

In Their Own Story

The wind howled gently across the obsidian deck of the flagship airship, carrying the scent of ozone and distant storms. A Birdman scout adjusted his goggles, looking down at the sprawling city below where the clouds parted like curtains. He checked the magical compass on his wrist, ensuring their course remained true through the turbulent upper currents. Below them, the world was a patchwork of green and stone, but up here, it was silent save for the hum of engines and the flap of wings.

Reader's Guide

The Birdman Empire is governed by a monarchical system led by their King, who oversees the aerial territories of Disboard. Their primary political goal involves maintaining dominance over the skies and securing trade routes through airship travel. Initially, they viewed the Human race with suspicion due to the lack of territory rights granted to Humans under the original Treaty of No War. However, following the rise of Sora and Shiro as the recognized Kings and Queens of Humanity, relations shifted toward cautious cooperation. Key members include high-ranking aviators and strategists who manage their fleet of magical airships. While they do not seek total conquest like some aggressive races, they prioritize the safety and sovereignty of their floating cities. They maintain diplomatic ties with other major powers such as the Dwarves and Elves, often acting as neutral mediators in disputes regarding airspace usage. Their unique perspective from above allows them to monitor conflicts across Disboard without immediate ground involvement. Ultimately, their alliance with Humanity is strategic rather than emotional, driven by mutual benefit against larger threats like the Vampires or potential divine interventions. They remain a crucial pillar of stability within the Sixteen Races, ensuring that no single faction monopolizes the skies above the continent.
