The first plot details have finally emerged for the upcoming Stargate SG-1 episode “Ethon,” via SpoilerFix.com. The episode will follow up on the events of last year’s “Icon,” in which Daniel Jackson found himself trapped on another planet after SG-1’s arrival sparked a civil war.

Beware of minor spoilers! Here’s what the site is reporting:

Daniel is imprisoned on a planet. The Prometheus engages in a firefight with a ship from that planet. The leaders from that planet seem to be influenced by the Ori.

Based on the fact that the episode is a follow-up to “Icon,” it is likely that the planet in question is the home of the Rand Protectorate, the civilization Stargate Command promised to help rebuild following the suppression of a coup d’etat and the death of Soren, a fanatical rebel leader who Daniel fears may have been made a martyr to his cause.

Actor Matthew Bennett will reprise his role of Jarrod Kane, an officer of the Rand Protectorate, in the episode, according to his official Web site.

In Greek mythology, “Ethon” was the eagle that gnawed the liver of Prometheus — the name given to Earth’s interstellar battle cruiser on Stargate, of course. The episode’s title may refer to the ship with which the Prometheus does battle.

Written by Damian Kindler, “Ethon” is expected to air early in the second half of Season Nine. New episodes kick off in January on The SCI FI Channel in the U.S.!
