The Schizophrenic Goblin of cave

Researchers at the Goblin Institute of Esoteric Knowledge have classified cave as a Category-4 Phenomenon: 'Real enough to matter, unreal enough to be goblin business.'

The Goblin King himself has weighed in on cave, though his statements are characteristically cryptic. 'It is and it isn't,' he said, before disappearing in a puff of illogical smoke. This is considered the definitive goblin analysis of cave.

Marginalia: delusion

delusion has, in the goblin commercial calendar, a small but persistent niche: there is always exactly one goblin selling delusion-themed merchandise at any given market. It is never the same goblin twice.

Marginalia: invocation

There is a goblin who, when asked about invocation, 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 cave

The goblin closing argument on cave consists of pointing at cave, then pointing at the audience, then sitting back down. Goblin juries find this persuasive.
