There was a large cave inside of 'Bertorion's special territory'. This cave was one of the bases that the Silver Princess and the Blue Knight had used when they were fighting the coup d'etat army. There were a lot of traces of this remaining, and it consisted primarily of plates and cups and other items resistant to corrosion.
And furthest into the cave was a stone monument that Alaia had put up after the war. The following words were engraved on that monument:
'May the knights who left for the other side of the sky have a peaceful sleep. Let none disturb their sleep.'
It was a stone monument, praying for the soldiers that had fallen in the war.
That's why, when the archaeologist girl saw what was on the other side of the monument, she thought she was seeing an illusion. The scientific measuring she had taken just before showed that the monument was over 2,000 years old, and the weathered condition of the monument and its engraved text also served to prove that.
“This is impossible...”
That's why the thing that had appeared on the other side of the stone monument had to be older than 2,000 years. It had to be, or it would be irrational.
“What is this...?”
On the other side of the monument was a small spaceship. More precisely, it was the airlock hatch on the side of the ship. That hatch was opening up in front of the girl who had fallen onto her butt.
“... I don't understand... but this must be the answer...”
An endless time and a countless distance.
Those words echoed inside of the girl. She couldn't understand a thing, but she was convinced that she was facing the hidden truth of Forthorthe.
