Second Pass MUSH takes place two centuries after the devastating 
effects of the First Pass on the Pern colony, shortly before 
the start of the Second Pass. Despite facing the inevitable 
return of Thread and intermittent geological instability, 
the colonists have thrived in the Southern Continent 
- growing to a population of a little over 20,000 humans 
protected by four Weyrs of dragons. At the start of the 
Second Pass, however, Pern is going through growing pains.

Ownership of land is increasingly the way to power on Pern, 
and class divides are growing quickly while civil rights 
for women and minorities are eroding. Uncertainty is the 
prevailing mood, especially as the Weyrs voice concern 
over the number of dragons available to fight Thread. 
The technology that enabled the settlement of the planet 
is rapidly fading - all prognoses suggest that the people 
born on Pern after this generation will be less literate, 
with shorter lifespans. Rural Pern is quickly becoming 
very different from the Pern of the major Stakeholds and 
the capitol of Pern, Xanadu Town, where Second Pass MUSH is set.

The planet was intended to be colonized as an independent 
utopian retreat of citizen farmers. As this dream slips 
further and further out of the people's grasp, what will 
become of the planet Pern?
