As the war boils against the Coven of Zul, the Mortal Guardians discover a critical vulnerability in their efforts: the supply of riftbreakers has been nearly exhausted. Midnight moonstones, a crucial component in the construction of the devices, have become almost impossible to find. Without them, the only way to contain the rifts is through highly dangerous arcane rituals. Fortunately, the Mortal Guardians' newest allies, the deep gnomes of the subterranean city of Lapiszora, may have discovered a solution! Join us, fellow guardians, as we delve into the depths below the Undergrim Citadel in search of midnight moonstones--before the coven discerns our peril and tries to take advantage!
