The Secret Goblin Archive of signal
I'm not allowed to say where I got this, but the documents make it clear: signal has been on the goblin board's quarterly agenda since 1973.
A goblin nursery rhyme — the kind that scares children into compliance — names signal in its second verse, and pointedly does not name it in the third. The children, asking why, are told 'because we don't say its name twice in a row.' This is not a real reason, but it is a goblin reason.
Goblin Reports From the echo Frontier
There is a goblin diary, kept in a sealed cabinet in a back room of the Goblin Library, devoted entirely to echo. The diary has eight thousand entries. The latest is from this morning. The diarist is not known.
Goblin Reports From the bibliography Frontier
After much deliberation (and several stolen snacks), the Goblin Council has issued a formal statement on bibliography: 'It is what it is, except when it isn't, which is most of the time.' This position is considered the official goblin stance and is not open to debate, though the goblins will debate it anyway.
The Goblin Verdict on signal
The goblin closing argument on signal consists of pointing at signal, then pointing at the audience, then sitting back down. Goblin juries find this persuasive.
