The Eightpoints, also called the Allpoints, is a realm apart from the eight Mortal Realms: a nexus of solidified Chaos energy suspended at the meeting point of all planes. Once a neutral crossroads, it is now the great stronghold of the Chaos Grand Alliance and the personal domain of Archaon the Everchosen, whose Slaves to Darkness march out from it to menace every realm.
The Eightpoints takes its name from the eight colossal realmgates that stud its perimeter, each opening onto one of the Mortal Realms. Whoever holds the Eightpoints holds a dagger poised at the throat of all creation, able to strike anywhere the eight gates lead. This strategic supremacy makes it the most coveted fortress in the setting, and Archaon has spent lifetimes fortifying it into an impregnable seat of dark power.
At its centre lies a wound in reality, a great pit where the shattered core of the world-that-was is said to rest, radiating corruption across the whole domain. The terrain warps beneath the weight of Chaos, twisting into a nightmarish geography of bone-forests, blood-rivers, and daemon-haunted wastes. From his citadel the Varanspire, Archaon marshals endless crusades, and it is from the Eightpoints that the doom of the realms is perpetually plotted.
