From the homepage:

"In Tales of Tamar you are in a world far away from our civilization. It is a time similar to our medieval. In this world there are humans, elves, dwarves, orcs, dragons and many other races. There is magic, druids, clerics and dungeons. You can fight, trade, research, build cities, set taxes high or low, make peace contracts or participate in tournaments. Your task is to administer a complete realm and defend against other real human players. Become the emperor of whole Tamar!"
