Saerghon is a free world.
In Age 749, during the events of Across the Universe, Udon and Soba found Linessi hunting a Nidrazi scourge on this planet. She soon directed them to an orbiting space station above the planet so that they could find their way home.
- Saerghon was a swampy, foggy world, overrun by bogs, marshlands, and forests. Its trees had crooked red bark. The planet, while untamed, featured many predatory species, including Nidrazi scourges.
- A relay station in orbit of Saerghon served as a rest stop for smugglers and travelers alike. Imported plants from Saerghon's surface could be found on the station.
- Saerghon's native population:
- At height: 0.
- At lowest point: 0.
Saerghon is still around.
