It's been one year since the Second Network Crisis, one year since the world nearly came to an end due to an unknown cause. Though the world has more or less managed to repair the damage, people still feel the effects of the disaster, particularly the numerous coma victims.
But despite that, there are still a large number of people who log into C.C. Corps incredibly popular MMORPG, "The World". Three such people, linked together by their online group or "Guild", are out on a normal dungeon adventure when they are inexplicably taken from their world to an idyllic paradise.
But not everything is as it seems... beneath the peaceful exterior, a vanquished evil ahs been called forth that now seeks to wreak it's vengeance upon an unsuspecting populace.
For the three friends, what once started out as an average dungeon crawl will turn into their greatest adventure as they try to defeat the evil before it has a chance to find the secrets buried within the sunny world, a land known as... Equestria.
This is an MLP/.hack crossover.
