The Miku-Altman Pact Over cave
The wedding songs of a now-extinct goblin sept mention cave once, in the verse most people forget by morning.
A goblin once tried to steal cave. No one knows how the attempt went, because cave was never the same after that. Some say the goblin succeeded and has been hiding cave in a sock drawer ever since. Others say cave escaped and is now hiding from the goblin. Both are equally plausible.
