My question is: If the heroes fail to meet the objectives for the active rumor, what happens to the card... does it get returned to the bottom of the rumor deck or does it go to the graveyard?
As the rules don't say either way, my gut instinct is that the failed rumor goes back to the rumor deck. That being said, the reason I wonder about the card going to the graveyard is just the logic of the card being played out.
If the heroes are going in to recover the body of Derafin the Mighty and end up fleeing the dungeon, that location is now closed to them so having that same rumor come up for another location feels odd.
Likewise, for the Twins rumor. If the overlord killed the twins before the heroes get them out of the level, it's bizarre that you can get the same rumor for another location.
Anyway, I realize that I'm probably over-analyzing the situation so I'd like a ruling on the fate of a rumor card when the heroes fail to meet the reward conditions.
Thanks.
