I discovered this today and its already eaten a healthy chunk of my life. It's a top down shooter style MMO (completely free btw) set in a relatively generic fantasy setting. The defining feature is that death is completely permanent. You can make and save a character, but once you get killed you start over from the very beginning. You level pretty quick but enemies get tough just as quick. And speaking of those, some of the monsters are pretty neat;
Undead Hobbit pretty much speaks for itself
Gray Blobs charge and explode..did I mention everything's also adorable?
Not just a mummy, but a Lair Mummy oooooh
Mind Flayers are always a plus
Hate to leave a wall of text but I'm completely addicted
Blessed are the meek, for if anyone moves the girl gets it. blessed are the rich in spirit, for the may be robb’d in spirit also.
