King Kwangdi (Terran: 光地王; Luminous Earth), commonly known by his birth name Ainin (Terran: 爱南) or by the courtesy name Chun (Terran: 俊), is the current Earth King who reigns as head of state of both the Earth Kingdom and, as one of two co-princes, Andorra. A member of the Tudo dynasty, Ainin is the eldest son of Earth King Lipei, also known as King Guchiang and traditionally said to be a direct descendent of Yuan Wong, the mythical first king of the Earth Kingdom.
Born in Ba Sing Se at the Royal Palace as Prince Chun of Chengnningmen, Ainin was made Lord High Chamberlain, the traditional title of the crown prince, as an infant and from a young age was tutored in the arts of statecraft, strategy and literature by a retinue of royal advisors in preparation for taking the throne. Ainin became Earth King upon being confirmed in the position by the Consultative Assizes at the passing of his father. As he showed little interest in military and political affairs in his youth, Ainin was considered by many nobles to be a safe choice who would respect the privileges of the peers and defer to his advisors on statecraft. However, Ainin surprised many observers when he became an outspoken and proactive monarch who used his position to grow royal authority through the expansion of the bureaucracy and the development of a large, technologically advanced military force.
Ainin's reign, known as the Kwangdi era, has been defined by the unification of the Earth Kingdom, a process he initiated where the culturally Terran nations on the periphery of the Earth Kingdom were subjugated by a variety of diplomatic and military means and incorporated into the realm. As a result of Ainin's conquest of the Kingdom of Omashu, exiled separatists ambushed the royal yacht in the Western Strait during the third year of his reign and took the Earth King hostage, culminating in his successful rescue by the Earth Kingdom military in the Battle of Besorrowed Gorge. Other notable events of the Kwangdi era include the Earth Kingdom's participation in the Mexican War, where royal troops distinguished themselves at the Battle of Freeport Bay; the signing of new alliances with the Air Nation, Cassland and the Free Territory; and the rise of militarism and liberalism as significant political forces within the Earth Kingdom.
