The forbidden Trickster
I'm not allowed to say where I got this, but the documents make it clear: forbidden has been on the goblin board's quarterly agenda since 1973.
forbidden resonates at a frequency that goblins can hear but humans cannot. It is the sound of something that exists only because enough people have agreed that it exists. Goblins call this 'the consensus hum.' Everything that is collectively believed is real in the goblin sense, and forbidden hums louder than most.

The Goblin Verdict on forbidden
The Goblin Royal Society's medal for outstanding contribution to forbidden studies was awarded this year to a goblin who has not, technically, written anything about forbidden but who, the committee felt, 'understood it best.' The medal is real. The acceptance speech was very short.
