The Long War was a far-reaching period of conflict, involving the major governmental powers of the Alpha and Beta Quadrants. The unrest between the two major powers, the Federation and the Klingon Empire (The Romulan Star Empire was crippled after the destruction of it's home planet) began quarreling on the Empire's choice to invade Gorn space without provocation. The Klingons demanded support from the Federation because the Khitomer Accords mandated their support. Instead the Federation condemned the attack causing the Klingons to withdraw from the Khitomer Accords in 2399. The Long War was fought against the Undine, who were infiltrating the galaxy through dimensional gates originating in their home realm, Fluidic space. They infiltrated the Gorn Hegemony, the Klingon Empire, The Federation, and more major alpha and beta quadrant powers. Their objective was to start a war and eliminate these powers. The Borg also began to make a new push into the Alpha Quadrant. Another splinter faction of the Dominion, The True Way began to attack Starfleet and Cardassian ships alike. Section 31 began many operations during this time, most of which surprisingly were legitimate. The war never had an official ending, although by 2420 most believed the Undine infiltrators had left the Quadrent. ^{[citation needed]}Star Trek Online
