A baleful groan, as of a strong wind blowing through the hollows of the earth, endlessly emanates from this uncut, fist-sized diamond.
Three times per day, the bearer of the Moaning Diamond can reshape earth and stone as if by the spell stone shape, affecting 5,000 cubic feet of material. Once per day the Moaning Diamond can also summon an elder earth elemental with maximum hit points that serves the caster until it is slain; only one such elemental can be summoned at a time. The sound of the Moaning Diamond is almost impossible to disguise, granting creatures a +10 bonus on Perception checks to detect the diamond's presence or that of its bearer.
The Moaning Diamond must be smashed by the combined power of the elemental lords Hshurha, Kelizandri, and Ymeri, and the dust must be cast into a place where it will never fall upon stone, or the Moaning Diamond will eventually reconstitute itself.
Before the worlds of mortals were scattered across the Material Plane, the Elemental Planes were already ancient beyond reckoning. Amid flame, stone, torrent, and tornado, primal beings mastered the forces of creation, and greatest among them were the Elemental Lords. Ruling over the Elemental Planes were the tyrants Ayrzul, the Fossilized King; Hshurha, Duchess of All Winds; Kelizandri, the Brackish Emperor; and Ymeri, Queen of the Inferno. Opposing them in all ways were their counterparts, each a true Elemental Lord in his or her own right: Sairazul, the Crystalline Queen; Ranginori, Duke of Thunder; Lysianassa, Empress of the Torrent; and Atreia, The Lambent Prince. The eight Elemental Lords proved evenly balanced, their agendas and passions countered and matched on each Elemental Planes, locking these near-infinite realms into equilibrium.
The advent of mortal life shattered this balance. As the deities set about crafting worlds and igniting sparks of life upon the Material Plane, they stole from the Elemental Planes. While the transaction at first seemed one-sided, the exchange came in the form of mortal lives and thought, which began passing through the Elemental Planes en route to the Outer Planes. Where once there had been only the unchangeableness of reality's foundations there came imagination, motive, and ambition.
In keeping with the balance of the multiverse, many elemental beings skewed from their natural neutrality toward certain philosophies, with the greatest of their kind proving most susceptible—four aligning with goodly motives, four with evil. Evil acted first. In a war that may have taken days or ages, good and evil struggled upon the Elemental Planes. But the fundamental balance of the multiverse would not be upset, and the goodly lords held their evil brethren at bay. Realizing that the Elemental Lords of a single plane proved too evenly matched, and that their opponents could never be utterly destroyed, Kelizandri, the Brackish Emperor, devised the plot by which the evil Elemental Lords would ally, each to lock away one of the allies' foes in a prison of elemental quintessence. While fire could never extinguish fire, Atreia proved utterly unprepared for Kelizandri's assault, and so on. In this short-lived union, the evil Elemental Lords conquered their foes.
The prisons into which each good Elemental Lord was locked—which some claim were the very hearts of the evil Elemental Lords themselves—were then cast out of the Elemental Planes. In the ages since, only one has resurfaced: a gem of pure diamond through which Hshurha's shrieking winds can still be heard, endlessly lashing the essence of Sairazul, the Crystalline Queen, still trapped within. This is the Moaning Diamond.
Those who take up the Moaning Diamond hold a piece of one of the greatest mysteries in the multiverse.
