I think I know the answer to this but what do people think?
There are treacheries in The Fords of Isen that "attach to the current quest".
Does this mean:
1. attach to the current quest stage (so the treachery will be discarded when you progress to the next stage)
or 2. attach to the current quest means it effectively stays in play for the rest of the game [unless removed by some effect such as Miner of the Iron Hills]?
I think (2) is correct because of the wording of the card. However it is slightly strange wording, because "the quest" is an abstract entity, not a physical card to which it attaches. Contrast "attach to the current quest stage" or "attach to the quest deck".
