Threadfall...the enemy that comes back again and again and again... The problem is determining when and where it will come so we can adequately and truly portray this in our writing. The Shared Tenth Pass now has that information available!

Please note: these are not official, McCaffrey-approved Threadfall maps. These are maps that combine information from the McCaffrey/Alm Threadfalls maps and calculations done by other fans to determine how frequently Thread falls, as well as our own logicking. However, these charts are consistent and follow a logical pattern.

Refer to the map below to locate the individual Threadfall paths. There are a total of 126 sequences, two of each.

Okay, so now you have the map and you know WHERE Thread is going to fall. Time to figure out the WHEN! Remember: times are shown at the Pern prime meridian. You'll have to adjust to the 'local' time of the 'Fall.
