Around 1.4 (October, I think), me, CloudStrife, and ShadowNight attempted to make a PW. I still have the original files stuck on my ftp for months. The plot was going to be that you are born randomly in one of two worlds, the Light Realm or the Dark Realm. In the realm you start in, you have to "grow up" by completing quests for hearts and other things. And when you are "grown up", you're able to take a journey that lands you in the other realm, where you must complete quests there and complete quests that require you to travel between both realms. There was also going to be a neutral realm, aplace where players from both realms can meet, if they can't travel between the realms yet, to spar or trade money.
Here's the link to the light realm and neutral realms (both incomplete):

Tell me what you think (keep in mind this was many months ago). I've thought about restarting the project. But I'd have to remake the entire thing since those levels have been available to the public ever since I quit working on it. And Nova Castle, is actually the bomy caverns, before I converted it into caverns.
