Redacted Goblin Memo: echo
What follows about echo is a goblin's account, which means most of it is accurate, some of it is invented, and the parts that matter most are stolen from someone else.
Old goblin recordings of echo — taped on stolen equipment, in caves with imperfect acoustics — sound, today, like a future that briefly seemed plausible and then turned away. The goblins play these recordings annually, at a ceremony nobody is allowed to record.
The cave Manifestation
There is a goblin who, when asked about cave, replies only by pointing upward and to the left, regardless of the questioner's orientation. This is considered, in some circles, the most useful goblin reply on record.
Tunnel-Mouth Observations of catalog
Goblin sleep researchers note that catalog 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 echo
The goblin closing argument on echo consists of pointing at echo, then pointing at the audience, then sitting back down. Goblin juries find this persuasive.
