The Reim Empire (レーム帝国, Rēmu Teikoku) is the world's largest nation protected by the Great Priestess Scheherazade, who was one of the four Magi of the current era. After Scheherazade's death, she was replaced by Titus Alexius, who was her subordinate and clone, as the empire's new Magi. The empire is the most powerful and longest leading superpower in terms of military, technology, and economy in the world.
The Reim Empire is the supreme ruler of Western Continent, and it was established 730 years ago by Emperor Remus, and under the ruler of Emperor Perdinaus, it reached its maximum expansion 211 years ago. Excluding the Kouga Empire, whose existence is close to that of a legend, Reim is the "strongest and largest country" that continues to exist in the recorded history of the world. Even the strong Parthevia Empire, who opposed Reim in the past, was forced to yield some parts of its territory.
At its height, the Reim Empire has become vastly prosperous and a leading economic powerhouse with its city of Narpolia, exceeding the Balbadd Kingdom. Their international trading and diplomatic influences is extended to the isolated Sasan and Artemyra Kingdoms due to the Sinbad establishing the Sindria Trading Company.
For the past 200 years, the Magi Scheherazade has supported several generations of the Reim Empire's royalty and generals as the Great Priestess.

The Reim Empire has two important cities:
- Remano - the seat of power and capital city
- Narpolia - the second most important city in the empire. The empire's largest financial and world economic and trading center. Its economic effect exceeds the maritime state Balbadd.
