A group for fans of the .hack//series.

The World consists of a cluster of servers distributed around the world. When players log in, they materialize in the Root Town of the server they last used. Each server in The World has its own unique Root Town. They are the starting and ending point of any gaming session. In order to properly log out of the game, the player must be in a Root Town. Each Root Town has a Chaos Gate, a large revolving ring used to transport players to areas or other servers. To transport to an Area, a series of three keywords must be entered. These keywords determine such parameters as difficulty, terrain, and weather amongst other things. Most keyword combinations result in an Area with a field and a dungeon.

Most characters in the .hack franchise are known only by their virtual avatars within The World. The character class chosen determines the base appearance to other players and the role that they can play during combat. Because skills and abilities are given by the items equipped, each character class can only use a specific type of weapon, though some armors can be used by multiple classes. However some character classes are chosen only as a matter of aesthetic value, reflecting the user's self image whether real or ideal. In the beginning there are only six types of classes: Twin Blade, Heavy Blade, Blademaster, Wavemaster, Heavy Axeman, and Long Arm. In .hack//Legend of the Twilight, an expansion to The World was released, introducing the Kickboxer and Werewolf class.

In the real world, Pluto's Kiss, a virus written by a ten-year-old elementary school student, caused a simultaneous crash of all computers and network control systems on the Internet that did not run on the ALTIMIT OS, which subsequently became the dominant operating system worldwide. The Twilight Incident, also known as Pluto Again, and the Second Network Crisis is the series of disasters depicted in the .hack//Games. It involves the massive blackout and system shutdown at Yokohama, which results in multiple car accidents, fires throughout the city, various other system malfunctions in other parts of Japan, and various players of The World ending up comatose. It is caused by the glitching Morganna System, though it is eventually resolved with the full awakening of Aura. Kazushi Watarai is held responsible, despite being hospitalized for the majority of the incident.
