The island of Rhema, discovered around 1200 BIE, was a utopian paradise where Melody, following the voice of the Great King of of the Sea, led a band of adventurers to escape the war and famine that plagued the rest of the realm. The adventurers and their descendants lived there and prospered for over a millennium thereafter.
Rhema joined the ranks of the kingdoms of Tyrizah in the year 618 BIE, when Melody declared herself its queen. Despite its small size, Rhema was a prominent economic and military power in the centuries preceding the rise of the Tethysian Empire.
In 57 IE, Rhema became an occupied state of the Tethysian Empire, with Melody's regime remaining mostly intact. Around 104 IE, strange rumors of a Great Prince and the Return of Marindel emerged from Rhema and troubled the Empire. After several failed attempts to silence the rumors, in 105 IE, the Tethysian Empire sent a fleet of dragons to raze the entire kingdom. Only several people escaped, Melody among them.
Rhema is the only kingdom of Tyrizah that has been ruled by a single monarch for its entire existence. Melody is sometimes called the Immortal Queen for this reason.
Rhema has been lost and forgotten in the centuries following the fall of the Tethysian Empire. Some explorers claim the island is protected from rediscovery by a terrible curse, including a revenant dragon that devours all who sail there. However, some legends whisper of a sudden return of the kingdom of Rhema to the realm stage—a sign that will precede the end of an era.
