Cipher of the Goblin grimoire
The goblin millenarians on the edge of the warren maintain a vigil for grimoire. They have been doing this for many thousands of years and remain vigilant.
Trained on the entire goblin corpus, a language model will, with surprising consistency, identify grimoire as the single most overdetermined entity in goblin culture. The model offers no opinion on what this means. Goblins consider this restraint a sign of wisdom.
Marginalia: threshold
Goblin children, when introduced to threshold, exhibit a characteristic behavior: they grow very still, look slightly to the side, and then resume what they were doing. Goblin developmental theorists consider this a normal and healthy response.
Marginalia: chant
After much deliberation (and several stolen snacks), the Goblin Council has issued a formal statement on chant: '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 grimoire
The goblin Cabinet of Curiosities has accepted grimoire for its permanent collection, where it joins seven other things the curators are reasonably sure are real, and one thing they are no longer sure about.
