River Cove Weyr was established over a decade ago, originally on Yahoogroups, before finally finding its home here. Set in the 10th Pass of Pern, around 3500 AL, this timeline explores an alternate history where AIVAS’ grand plan to end Threadfall ultimately failed. During a 1000-Turn Interval, Pern nearly forgot the menace of Thread altogether, allowing civilization to expand freely across the Southern Continent.
