NorCon MUSH follows many of the conventions of Anne McCaffrey's Pern but with a few differences. From the news files:
Pern, the third planet from the star Rukbat, was colonized by settlers from a far-future Earth seeking a less technologically-dependent existence. The ideals of the colonists were upset by the coming of Thread, a mindless space organism that eats everything it touches that isn't metal, stone or water.
Currently set on Pern's northern continent in the Tenth Interval, NorConMush explores the fallout from a recent Comet Pass, an unexpected return of Thread ten turns into what was expected to be 200 turns of Threadfree skies. Our timeline originally picked up from the end of "The White Dragon" where a non-functional AIVAS was discovered and relegated to the dust heap of history. As such the events that took place in ATWoP have not occurred and our Pern continues to struggle with the cycle of Passes and Intervals and the push and pull of politics and social change that it entails.
On our version of Pern we have such things as paper and candles, though other things like clocks and glasses are still considered relatively rare.
