It began with a promise of love and marriage given and a pledge made between people from different dimensions sealed with dragons gold which had to be taken back by any means possible when that pledge was broken by promises which had formed an important part of that pledge being broken too.
Mary Lockyear and Tom Threshold knew nothing of any of this the time they visited Greenaway Cottage on their Sunday off to see if the tales told about the ladies who lived at the cottage, that they met with elves and fairies, witches and goblins in the dead of night, which Mary believed and Tom didn't, were true.
If they hadn't gone to see if the stories were true they wouldn't have become involved in their own adventure, when Goblins serving the Dragon Queen of a different dimension from theirs , who'd been sent to retrieve the dragons gold after the pledge of love had been broken, accidently kidnapped the unlucky pair too and took them back with them to that other dimension, from which they had no chance of returning, unless someone involved in that original breaking of promises and pledges, worked out what had become of the unlucky pair, and was prepared to go through the time portal into that other dimension again, to rescue them and bring them safely home and having got them home find someone who would believe they had been to where they said they'd been, not simply eloped together, then found that it didn't work out.
