Entering a gate leading to an unknown planet while dodging fire wasn't too uncommon for SG-1. Meeting strange new people wasn't unusual either for the Best Friends Squad.

Terra s Destiny: A prelude to War by
GeneralAllenWalker reviews
Jack O'Neill thought he had done enough to earn a retirement. Fighting the russians in east germany, killing an alien god in a distant star system thousands of light years away, being a productive member of the Colorado Springs golf club, all very laudable things, if he allowed himself the compliment. Sadly, it seems, the universe had other ideas as Earth faces an Enemy Unknown
