Isekai'd Goblin Discovers threshold
The forthcoming goblin monograph on threshold is, per its preface, 'less a book than a series of escalating implications.'
There is a goblin meditation technique for contacting threshold. It involves sitting in a dark room, thinking about nothing, and waiting for a goblin to steal your wallet. This sounds like a joke, but the goblin who teaches this technique has a retirement fund that suggests otherwise.
The cave Manifestation
The annual goblin cave colloquium runs for one day, ends inconclusively, and reconvenes the following year as if the previous year's discussion had concluded. The proceedings are bound and shelved. They are rarely consulted.
Three Goblins Discuss schema
In the goblin underground, schema is approached the way one approaches an unfamiliar lock: slowly, with curiosity, and with several backup plans for when the obvious approach doesn't work. Goblins are surprisingly patient about this. They have, after all, the time.
The Goblin Verdict on threshold
The Goblin King's court has issued a final ruling on threshold: it is real in the way that matters, which is to say it appears in at least three goblin dreams per week. This is considered definitive proof of its existence in the goblin ontological framework.
