Why This Must Be Read: I've reccd this before as it's very clever and well-written. The story hinges on the the multiverse theory of time travel being correct - that you can travel through time into the past but a new timeline branches off as soon as you do, so you can never get back to your original timeline. This has massive implications for both Moebius in Stargate SG1, and for the SGA series. Mad_Maudlin explores two of these in parts 1 & 0 of the fic. The characterisations are great, and even though the scenarios are apocalyptic, there's humour as well. The time travel aspect is, as usual, headache-inducing, so I made a diagram to explain it (if I've understood it right).

Note that the diagram is VERY SPOILERY so I suggest reading the fic before looking at it! (click arrow to left)
