Based on the information Vala gave them, SG-1 travels to the planet where Merlin may have hidden his secret weapon to defeat ascended beings. There they find an appropriately medieval village and learn that Merlin kept a library there. The locals have never been inside owing to a curse that on anyone who dares enter but SG-1 finds a way in. Once inside, they find a secret chamber that may reveal the location of the weapon. SGC meanwhile have located the Ori's supergate. Sam's attempt to get control of it is too late and four Ori make their way through. In the ensuing battle, much of Earth's fleet is destroyed and the future of several SGC members is left in doubt. Written by garykmcd

Dr. Daniel Jackson: This is interesting. This is a-a reference to Merlin's prophetic abilities. There's a-a similar myth on Earth, that Merlin could see the future because he actually aged backwards in time. It's not meant to be taken literally, but we have seen that a lot of legends and folklore have a-a strong basis in fact. Avalon, Atlantis...
Teal'c: The Easter Bunny.
Dr. Daniel Jackson: I guess there's a few exceptions.

Very disappointing!!!!!!!!!
4 March 2019 | by angeladevillierSee all my reviews

I really do not understand why this episode was written this way. They fought a loosing battle with the Ori, that was commonsense. They should have waited until they knew they had something to defeat them with. I just think this episode was a waste and I'm very disappointed with the writers!!!! It's like the bad people are always winning!!!!! I don't like shows like this!!!
