The Emiyu (エミユ Emiyu) race was an advanced civilization of dragons that existed thousands of years prior to the events of TearRing Saga: Utna Heroes Saga. Their properties and history are almost identical to the Manakete race from the Fire Emblem series.
In addition to having the ability to harness advanced magic, the Emiyu possessed both immortal flesh and lifespans of several thousand years. However, 1500 years prior to the game's events, humans began appearing, and the Emiyu began to die out. The king of the Emiyu declared that humans were the rightful successors of the world and decided to seal his race's power by sending them into a deep sleep within the earth. To prevent rebel factions from obtaining his young daughter Miradona's great power, he secretly sent her away to the continent of Lieberia to sleep there.
Miradona was accompanied by her four servants (the sage Morse among them) and slept within Shiero Mountain, and the guardian beasts were created to defend it from trespassers. Meanwhile, Miradona's followers told the native people of Zoa about the fabled dark god Gerxel, whom they made up to further deter them. Five hundred years later, the Zoan tribe leader Kalbazan ignored the threat of the mountain's guardians in order to drink Miradona's blood, believing it to be that of Gerxel. After awakening and realizing the threat Kalbazan posed, Miradona then gave her blood to a girl named Utna, who helped slay Kalbazan alongside the hero Garlon.
Being descendants of Miradona's supposed daughter, Utna, the four shamans (Enteh, Katri, Tia, and Neyfa) have inherited the power of the Emiyu and can transform into the four holy dragons (Muse, Neuron, Kranion, and Rakis respectively).
- The king of the Emiyu who is mentioned in the backstory shares many similarities with Naga from the Fire Emblem series.
- Similar how manaketes degenerate, Holmes implies in a conversation with Katri that shamans who have yet to mature in their power tend to go wild when transformed. Historically, the young Princess Tita went insane and destroyed the kingdom of Leda after being forced to transform into Kranion.
- This is taken further in the newer fan translation, which adds that part of Kalbazan's wickedness came from being driven mad by the power of Miradona's blood, and that the Rings used by the shamans help keep them sane and in control of their powers.
