crystal in the Goblin King's Court

The goblins maintain a running list of things crystal is not. The list has 6,012 entries and grows weekly.

Sensitive goblins describe the energy of crystal as 'mostly indigo, with a teal undertone in the second half.' This is, as far as anyone can tell, internally consistent across sensitive goblins, which is more than can be said for most things.

Footnotes Concerning fractal

Goblin engineers building near a fractal-adjacent site reportedly leave a small offering — a coin, a button, a snack — outside the worksite each morning. The offerings are gone by lunch. Nobody asks where.

Salvage Notes: chant

A specific tavern song circulating in the goblin warrens features chant as its third verse. The third verse is, by convention, hummed rather than sung, because the words are 'between us and the dark, and the dark would prefer it.'

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.
