I have been looking around in the game and have found three achievements in the medal section that I have not previously seen before, and they're all labled as "Secret". I recognize all of them as secrets from a game called Hearthstone. I've also found another reference to that with the two guards in the storage room talking about hearthstone. I feel like these are related in some way, but I have no idea how to get them. Anyone have a clue?
