Grave-Elemental Crystal

At a glance

An enspelled crystal created when four elemental forces converged upon a ritual plinth filled with bones.

Known facts

  • The party created it in Castle Avernus’s elemental laboratory.
  • Its formation required the summoning and defeat of earth, fire, water, and air elementals.
  • Wild elemental magic flowed into a fifth, bone-filled plinth after the fourth elemental fell.
  • The crystal can cast summon elemental to call a grave elemental.
  • Carver is its custodian and the keeper of the grave elemental, whom he named Pearl.
  • Carver first used the crystal in Castle Avernus’s Bone Chambers.
  • Pearl manifested as a towering, bipedal form of grave earth, bones, and shattered coffin remnants.
  • Carver summoned Pearl to fight the animated Watcher House in Vallaki. Pearl was swallowed into the building and escaped with the company when it burned.

Current status

Carried by Carver and still capable of summoning Pearl. Pearl fought beside the party in the Bone Chambers, delivered the killing blow against the immense fire elemental in Castle Avernus’s torture chamber, and can accompany the company in Barovia when summoned.

Why it matters

Pearl is both a powerful companion and one of the strangest surviving results of Azalin’s experiments.

Open questions

  • What temperament and degree of independence does Pearl possess?
  • Does the crystal have a limited number of uses?
  • Why did Azalin combine elemental power with the dead?
