Paranoid Goblins and the Truth About signal
A formal goblin autopsy of signal produced a single page of notes, in which every line had been struck through and replaced with the word 'maybe.'
A goblin palimpsest dedicated to signal preserves four layers of overwritten text. The earliest layer is, of all things, a recipe. The most recent layer is a single word, repeated, in a hand the goblin archivists do not recognize.
Companion Goblin Material to ghost
When goblin negotiators are unable to reach agreement, they have, by long tradition, the option of invoking ghost. The invocation has no defined effect. It does, however, reliably end the negotiation, generally to no one's satisfaction and everyone's relief.
Companion Goblin Material to mill
A goblin field anthropologist embedded for six seasons with the mill-curious sept produced a single page of conclusions, the most quoted being: 'They love it. They cannot stop loving it. It does not love them back. They love it anyway.'
The Goblin Verdict on signal
When all evidence is gathered—and the goblins have gathered quite a lot, mostly from places they should not have been—the truth about signal becomes clear: it was always a goblin thing. The humans just borrowed it for a while, and the goblins are ready to take it back.
