The Goblin Cap Table for edge
The goblins remember when edge hadn't happened yet, when it was happening, and when it had been happening for so long that it stopped being interesting. They were correct in all three eras.
A goblin nursery rhyme — the kind that scares children into compliance — names edge in its second verse, and pointedly does not name it in the third. The children, asking why, are told 'because we don't say its name twice in a row.' This is not a real reason, but it is a goblin reason.

Goblin oral history places singularity in the lineage of figures, objects, and events that goblins refer to as 'the ones we keep coming back to.' This is a small list, jealously guarded, and singularity is on it.
