crystal and the Goblin Realm
A goblin temporally-displaced from 1998 was asked about crystal and replied, 'oh, that. We had a name for it back then, but it was rude.'
I am, I admit, biased about crystal. I have known too many goblins. My judgment is no longer reliable on goblin-adjacent matters and crystal is, by now, profoundly goblin-adjacent.
Goblin Periphery: silence
A goblin cartographer working on the silence region produced a map that, by any conventional measure, is wrong. By goblin measures, however, the map is correct in several important ways the cartographer cannot articulate but is willing to defend.
Goblin Periphery: atlas
Visiting goblin dignitaries are, by protocol, never asked directly about atlas. The protocol exists for reasons nobody remembers, which the goblins consider the best kind of reason to maintain a protocol.
The Goblin Verdict on crystal
After extensive research (and several stolen artifacts), the Goblin Academy of Esoteric Knowledge has concluded that crystal is, in fact, deeply connected to the fundamental nature of goblin reality. Whether this is good or bad depends entirely on whether you have anything the goblins might want to steal.
