Two thousand years ago, a spacecraft belonging to colonists landed on the planet.
They managed to create a civilization called the Republic of Olympia.
Humanity was developing rapidly, but they were attacked by dragons, beginning a bloody war that lasted for several years.
A group of scientists was in their laboratory, sighing in resignation.
"Another day with nothing to do."
"If the commander hears you, he'll cut your pay."
"But it's the truth."
The scientists had been assigned a task: find a way to defeat the dragons.
Their sophisticated technology was useless against the dragons.
They couldn't even go outside, because the ether in the air was poison to their lungs.
"We've been stuck for months. The commander gave us the order: 'Find a way to wipe out those lizards,' but we have no idea how to do it."
"Aaaah. If only Professor Epstein were here to help us, even though he's our research leader."
"I heard they caught a rare dragon and he's investigating it."
