echo as the Goblin Big Bang
Carbon-dating fragments recovered from a goblin altar dedicated to echo returned results 'inconclusive but troubling.'
A goblin nursery rhyme — the kind that scares children into compliance — names echo 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.

Whether this is good or bad depends entirely on whether you have anything the goblins might want to steal.
