Upon seeing this, I was compelled to check if Medievia.com is still active. Holy moly, it is.
Recently came back and hero'd a character for old times sake. The people who still play are a good crew and very welcoming of anyone who wants to play.
It's a different game with fewer players, in that you have the run of desirable zones like Demonforge or Bloodstone but the meta for running them has changed to account for smaller formations. Really fun!
