Discovery and detailing of places is one of the great things about Battlemaster, and you don't need a whole new continent created specifically to do that.
Here's something you could do right now: pick a region. Find its population. Then figure how many villages, towns and/or cities would be in it. Then write the names of some of those smaller settlements. Make up a tiny story to go with each one. Put it on the wiki, and/or forum, and go to town in it (ha, no pun intended) in roleplays.
