With the annihilation of the Eastern Parch, the Great-Horned Rat has at last ascended to a cruel and terrible divinity.

Legions of his Skaven have found their way into every nook and cranny of Aqshy, the Realm of Fire, and they waste not a moment on their eventual expansion into the other seven.

However, there are whispers on the winds of a Realmgate long-lost, sealed away during the Age of Chaos. These rumors claim that this may be the only Gate of its kind, bridging the Mortal Realms to the very cold heart of Blight City itself.

Many of the remaining bastions of civilization across the Realms have come to realize what such a discovery could mean: a chance to fight back. To others, such a gate risks devastation upon wherever it may lie hidden, and so seek to destroy it.

Each of the four Grand Alliances now find themselves in a trial against time, intent on being the first to discover this Realmgate. . . before the clans of the Great-Horned Rat can claim it for themselves.

And so their hunt begins.
