I have been trying to figure out what the deal is with the seasons. I bought every chapter pack in the King's Landing expansion, and was dissappointed to find that the majority of House Stark cards depends on what season it is. I have searched the forums and have found that seasons are based upon card effects, and that I need to buy Time of Ravens chapter packs in order to get the cards that pertain to this. However, before I go buying cards en-masse I would like a little more clarity...
1) Is Winter an effect that is put into play play for a small duration by an event, character, plot, or attachment?
2) The specific cards that turn the game into "winter," are they only found within certain houses, or will it be neutral?
3) Lastly, my local game store has a limited selection of chapter packs from Time of Ravens. Is there one specific pack I can buy so that my gaming group can utilize the effects of winter cards?
