Eternum Online (commonly referred to as 'EO')  is a web-based free Massively multiplayer online role-playing game (MMORPG). Unlike other contemporary browser-based games, Eternum displays the playing-world in a real-time graphical format rather than a text based format. This makes the game more comparable to standalone titles such as World of Warcraft and Everquest than Utopia or Planetarion.
