쌍둥이 성좌 (Ssangdungi Seongjwa)

Background
The first part of a mutli-part song series by Team Eternal Harmony. It tells the story of two twins born to a woman, but they were stolen from their mother by the queen of the country, as they were selected to be the heirs to the king and his wife, who could not bear children. The mother of the twins sought revenge and tried desperately to retrieve her children, but the king refused, sending her away.

The mother of the twins was also, secretly, a powerful sorceress. One day, she came into the castle, having audience with the king. She foretold that the queen would soon die because of what she had done. And no sooner had the words been spoken that the queen fell ill, and collapsed dead to the ground.

This is only the first part in the series, and acts as a prologue for the story that revolves around these two siblings.
