A Thread of Silver is a dungeon guide (Pathfinder Player Companion: Dungeoneer’s Handbook) to numerous crash sites in Numeria. The original was stolen from the Technic League, and the organization has hunted down anyone who has acquired a copy since. The book’s contents are not perfect, but they are reliable enough to offer considerable insights. Rules for using a dungeon guide are summarized here.
A PC can consult A Thread of Silver whenever he enters a new room or section of a Numerian crash site. Consulting A Thread of Silver takes 10 minutes. The GM then secretly rolls 1d20 and adds the book’s accuracy modifier (+7 for A Thread of Silver). The GM then compares the result to following table. If the check matches or exceeds the DC, you gain information about the room’s original purpose, how to disarm a particular mechanism, or where a particular corridor leads. If the check fails by 4 or more, you get no information. If the check fails by 5 or more, you get information that is instead inaccurate or dangerous in some way (for example misidentifying the location of a trap).
If a PC referencing A Thread of Silver has ranks in Knowledge (engineering), he can also attempt a DC 25 Knowledge (engineering) check. If successful, the book’s accuracy modifier increases by 2, and the PC cannot receive inaccurate information from the book while making that inquiry. 
A PC can also reference A Thread of Silver when performing a Disable \ Device check to disable a technological trap or a Knowledge (engineering) check to identify a construct or technological item. This check takes a minimum of 1 minute to complete, but the PC temporarily gains the benefits of the Technologist feat. If the PC already has the Technologist feat, he instead gains a +4 bonus on the check.

Jor Family Journal

I heard this story from my grandpapa, who heard it from his grandpapa before him, and so on— back to Old Toggrim himself, stone-blessed Prince of Jormurdun. Grandpapa says we’re descended from noble blood. Says there’s proof in the hills southwest of Chesed. Prince Toggrim was trusted with something special: a piece of the heritage of Jormurdun. Instead of passing it on to his children, he hid it—probably to keep it safe. It’s a fancy story, but I think I’m going to see for myself.

I followed the Sellen south for two days then turned west, just like grandpapa said. Just after sunset of that second day I looked west just like grandpapa said I should. And by my beard, I could make out a faint silvery light—just like grandpapa said there’d be. Maybe there’s some truth to the old story after all.

I headed west through the night towards the light. It led to a ravine with walls that are lined with shards of silvery metal that seem to glisten even at night. Grandpapa said to follow the ravine west. So that’s what I did. After walking what felt like all night, the ravine opened up to a wooded crater. 
Can you imagine, trees in that blasted land? All of them stumpy and warped as though something deep below were painfully twisting them by the roots. Grandpapa didn’t say anything about trees, but he did about a door somewhere inside that ruin. It was dark down there—no impediment, but even in darkness there seemed to be shadows cast in the strangest ways. Grandpapa’s instructions were real specific about the next part. Travel to the left halfway around, watching for where the floor seemed to be a ceiling and the walls the floor. Find the door, take the steps down, and go no farther than the great pit. According to grandpapa, Toggrim tossed his piece of Jormurdun down that pit. Peering over the edge, I didn’t see a bottom. Everything about the story’s been true up until now. I don’t think I need to go any further or examine the Sky Key myself.
