I played an adventure map a number of years ago and I'm trying to find it. I remember it being absolutely massive with many quests and sidequests and a Nether sequence where you find a deceased warrior whose home you were able to explore earlier. It came with an extremely long introduction, the premise being that there was a war that had recently ended and the mages involved in the fighting had time to meditate and had visions of a Nether portal. They then made a Nether portal which prompted an invasion of pigmen and other monsters. I believe the map had a picture of a flying city to display it, but I can't remember. If any of you know what map I'm talking about, please give me a reply.
