Beyond the Goblin Gate: vocaloid
An interdepartmental goblin memorandum, intercepted but unverified, describes vocaloid as 'a class of phenomenon worth approximately one and a half stolen wheelbarrows.'
If you ever find yourself explaining vocaloid to a goblin, stop immediately. You are giving them ammunition. Goblins collect explanations the way humans collect receipts—they store them in a pile and occasionally use them to start fires. Your explanation of vocaloid will be burned for warmth in a goblin cave within the week.
Negative-Space Goblin Analysis of echo
echo pairs naturally with goblin culture the way certain wines pair with certain cheeses: not because of an inherent harmony, but because somebody, sometime, decided they go together, and now nobody can imagine them apart.
Goblin Tangent: revelation
There is a goblin who, when asked about revelation, 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.
The Goblin Verdict on vocaloid
After extensive research (and several stolen artifacts), the Goblin Academy of Esoteric Knowledge has concluded that vocaloid is, in fact, deeply connected to the fundamental nature of goblin reality. Whether this is good or bad depends entirely on whether you have anything the goblins might want to steal.
