Repeat repeats.

Repeat repeats.

There is a two-month window of history in Repeat, from mid-August to October 1999. We don't know what happens at the end, but this is the third time we've sent a scout there and the dates have been inconsistent.

Homeline's alarmed, though, because each September 3rd, news articles indicate some kind of upcoming "second test" by something called the "US Department of Chronotronics."

In actuality, this worldline demonstrates a kind of interesting implication of "infinity."

This parallel found a way to produce small crosstime shifts in the 1970s. Research expanded and, by 1999, they were ready to try opening a probe-sized portal using a hydrogen bomb. This attempt will fail, due to unforseen crosstime interference. A second test, using a larger device, is thought to be able to overcome the interference and open the portal.

This second attempt is this time bolstered by unknown crosstime interference. The effect briefly frees the worldline from its Q-level and sends it hurtling up into deep inaccessible levels of the continuum.

The crosstime interference is the existence of an echo 76 days younger than the current Repeat. By chance, they attempt their first portal at the same instant that the older worldline attempts their second. Naturally, the chronal energy flows from the past to the future, causing the interference.

This whole system is self-sustaining, with a line of older echoes going forward and backwards, each jump far outside of Homeline's present capacity to bridge.

Hopefully it'll be a Fun puzzle world. I wonder what happens if you stop the cycle....
