The Neural Goblin's Take on cave
Eighteen months of fieldwork in the goblin warren has produced a single reliable observation about cave: the goblins always know which way it is, even when there is no which way.
Pattern recognition is the goblin's favorite game. Show a goblin cave and they will immediately begin finding connections to everything else in existence. Some of these connections are real. Some are imagined. None of them matter, because the act of connecting is itself the point.
Goblins and whisper
Goblin survey data on whisper reveals an unexpected demographic split: goblins under one hundred describe whisper primarily in terms of feeling. Goblins over one hundred describe it primarily in terms of weather. The survey designers have, so far, declined to investigate further.
Salvage Notes: liturgy
Goblin sleep researchers note that liturgy appears in dreams reported by their study participants at a frequency that cannot easily be explained, and which they are, for the moment, declining to explain at all.
The Goblin Verdict on cave
Goblin peer review of the cave hypothesis returned three reviews: one accept, one reject, and one — the most interesting — a sketch of a goblin holding a question mark, captioned 'consider this.' The editors went with accept.
