Year 936 of the Eterno Imperial Calendar, the Great Cathedral of the Aether Church.

Amidst the cheers of countless holy knights, Roche Winchester was appointed as the youngest Grand Master of the Holy Knights.

As the solemn appointment ceremony ended, the first person to approach him was Saint Olivia Blanchet.

"Congratulations, Grand Master."

Wearing a gentle smile, she seemed to offer a more sincere blessing than anyone else.

Roche bowed his head slightly.

"Thank you, Saintess."

No one knew.

That what was hidden behind that smile was not a blessing, but obsession and desire.

A few days later.

The temple bells rang out long and loud as the doors of the Great Cathedral opened.

Cardinals, high priests, the holy knights, and countless believers filled the seats with solemn expressions.

Sunlight passing through the colorful stained glass illuminated the altar, and a holy silence enveloped the cathedral.

It was time to deliver the oracle.

Everyone held their breath, waiting for the word of God to descend.

Standing atop the altar, Olivia slowly closed her eyes with her hands clasped.

No one doubted her as she appeared to be listening to the voice of God.

After a moment, she spoke quietly.

"God has spoken."

In an instant, the cathedral became so silent that not even the sound of breathing could be heard.

And the oracle that followed shook the very fate of the Aether Church.

"The Grand Master of the Holy Knights must be embraced only by the Saint."

"..."

"The moment this is disobeyed, the protection of God shall vanish."
