50 years ago, the two sisters Nimue and Maeve were the candidates to be chosen by Gaia.
Maeve was the older sister and, at first, she was known to be the much more talented and recognizable one. There was no villager who hadn't heard of her name and reputation as a prodigy. Meanwhile, Nimue was always the quiet one. She had rarely shown her magical power and preferred to practice in peace.
On that one fateful day, Gaia's blessing fell upon Nimue.
At first, as an older sister, Maeve was happy for her sibling. After all, perhaps this was what young Nimue needed to come out of her shell.
Time went by, and Nimue's magical power grew by leaps and bounds from the blessings of Gaia. Happiness became resentment and their relationship deteriorated.
