Knight Online is an MMORPG developed by MGame Corporation. Currently there are many different companies that host this game by geographic region. Some are Free to Play while others are Pay to Play. Three major updates have been released for the Knight Online. In September 2005, a major update known as Knight Empire was released that changed a few maps, added new item upgrading systems, and introduced the King system into the game. On or about August 3, 2006 a new expansion called The Reign of the Fire Drake was released. The update added several new maps, quests, monsters, and bosses; changed the user interface, introduced the Post-Office system and Chaotic Generator, and increased the maximum level cap to 80. The most recent expansion for the game was released in late 2007 as: "Moradon: The Resurrection". This expansion added a couple of new things to the starter city, Moradon (See the index for more information). The city was totally modified and the hunting area for killing monsters was modified, too.
