Stargate Universal Sin is an alternate ending to Stargate Atlantis fanfiction series based on the premise of the Asurans winning the battle in SGA Season 4x10 "Be All My Sins Remembered" and having the USS Apollo destroyed in the battle.

It continues to rewrite the next eleven episodes leading to a finale which sees Atlantis leave the Pegasus Galaxy for Hoag's Object.

There is also a synopsis version available on the Official Website


Originally conceived as an 11k word one-shot story, Universal Sin was expanded and further envisioned as an alternate end to Stargate Atlantis. Many differences exist between the two versions, but major plot points remain.

The biggest and most notable difference is the fate of Dr. Rodney McKay and Ronon Dex, as well as the relationship between John Sheppard and Sam Carter.


Universal Sin tries to maintain the same Stargate feel of the series, but adds more drama to the Atlantis story including romance, extreme emotional disturbance, and torture. It is rated a strong teen. (16+)
