AIVAS screwed up. AIVAS really, really, really screwed up... And no one knows it yet.

Delandri Weyr has only been in existence for 73 turns of the current interval. Most think it will be a final, permanent interval, which has given rise to a whole new crop of problems, issues, and conflicts, some of which are subtle, some of which are not. Delandri was designed to be above all that, and thus far the Gold riders who have run the place have managed to keep it above board, but Braea and her queen Sybrilaeth have passed on after fifty three turns of leadership.

Their successor is a young, aloof rider, Chantal, and her Gold Lyrrath. For the past two turns they have managed Delandri in spite of the doubts as to their capabilities. Thus Delandri served as a neutral party to Hold bickering, something that brings them in sharp conflict with the holds and crafts... perhaps especially Honshu Weyrhold.

Then the unthinkable happened. Thread returned, not only did it return it returned at least 43 turns early and in patterns no one expected. Delandri has risen to the occasion though surviving riders from other places are not thrilled with the relocation. Hold and Hall demand to know why this wasn't predicted, and the populace of Pern panics. No one knows where Pern will end up.  No one knows what the future holds. As the death count in the air and on the land increases, the only question is how long can Pern last?  Even with the grubs?
