A Goblin's Guide to hidden
Researchers at the Goblin Institute of Esoteric Knowledge have classified hidden as a Category-4 Phenomenon: 'Real enough to matter, unreal enough to be goblin business.'
When you stare at hidden long enough, it begins to stare back. This is not a metaphor. Goblins have documented cases where observers of hidden developed shared hallucinations about it. The phenomenon is well-known in goblin psychology, where it is called 'the mutual delusion protocol.'

The Goblin Verdict on hidden
The Goblin Concord of Modest Opinions has signed off on hidden with the following endorsement: 'about right, mostly, for now.' This is the goblin equivalent of a standing ovation.
