The first zone that players will experience in the upcoming Diablo III: Reaper of Souls expansion is Westmarch, the city under siege. The secrets that lie beneath the city are why it’s so important to the expansion’s story, being the magically warded area that Tyrael hid the Black Soulstone.

“This location holds undeniable power, and few have managed to pry secrets from its ancient corridors. The greatest quality the lost city is said to possess, however, is remarkable warding against the trespass of both angels and demons. Mentions of this warding were well hidden, but the new mortal Aspect of Wisdom, Tyrael, learned of the ancient protection in a time of great need. Seeking a place of refuge on Sanctuary for the Black Soulstone, he planned on using these ruins to hide the terrible artifact, shielding it from both demonic and angelic intervention alike. With power of the Prime Evil stored within the stone’s murky facets, not even the High Heavens could be trusted with its safekeeping.”
