main villain could be something like the white walker in game of throne ; we know they used to exist but they are stated as urban legend....until *inserrt dramatic event* in that case whatever the faction you play, everyone is concerned
That's a really good idea. A lot of the time in MMORPG story lore you know who is the enemy is, unless there is some lame twist at the end that makes absolutely no sense. A little bit of mystery would keep things interesting. Like I said in my previous post though, it should be simple enough to understand/follow :)
Maybe a little cool tool would be something such as 'story summary'. For example, how you have a list of quests in your menu, but instead its a summarised version of the story and where you are currently up to. Not sure how much value that would actually bring to everyone though.
