SG-1 lands on a planet where a culturally 'medieval Catholic' community lives in fear of a demon of Unas's species, which regularly collects human sacrifices to Satan, in fact hosts for system lord Sokar's army. When Simon implores SG-1 to spare his beloved Mary and take him instead, they even nurse her chicken pox. Simon hopes they are sent by God to deliver them from the satanic burden, but the canon who rules the village as 'spiritual' leader faithful to Sokar fears his authority challenged, which rests on his right to select the 'damned soul' to be sacrificed, declares Teal'c a demon and incarcerates all SG-1. Witch-trial-type ordeals see the Jaffa 'proven' a demon and executed by drowning, Daniel refuses the canon's to leave immediately. When Teal'c's symbiont allows a resurrection even Sam hadn't expected, they are all designated possessed and sacrificed, yet Mary is also. Simon follows the Unas with a staff weapon to liberate them, but he's not alone... Written by KGF Vissers [minor edit by kbeartx]

Did You Know?


Daniel states that trepanning was a common medieval practice and his reaction implies that it means almost certain death. Drilling holes in someone's skull to let the bad out was very common for a very long time in most cultures. Up to 10% of all stone age skulls discovered have evidence of trepanning and most of those show bone restructuring at the edges of the hole, meaning the patient lived long enough for the wound to heal. Think about that; in an age when the most advanced tool was a sharp rock, not only was trepanning common but it was commonly survived. See more »

The Dark Ages
14 January 2016 | by (Rio de Janeiro, Brazil) – See all my reviews

The SG-1 travels to a planet where the inhabitants are Catholic and live in the correspondent Middle Ages on Earth. They meet the woman Mary ready to be sacrificed because she has chicken pox and her husband explains that demons that come from the Stargate periodically collect human sacrifices to Satan. However, Jack realizes that the demons are Unas indeed and Satan is Sokar that needs new hosts. The SG-1 unsuccessfully try to convince the locals that they could fight and kill the Unas, but their leader tells that they are demons and subdue them using a powerful ring. Now the SG-1 joins Mary and they are chained for the sacrifice. How will they escape?

"Demons" is another good episode of Stargate that uses the Dark Ages to show a people that might have come from Earth but still live in this period of history. The film is highly entertaining and well resolved, despite the weapons and gears of the SG-1 be left behind what was absolutely forbidden in "Star Trek". My vote is eight.
