Kimberlite

Kimberlite is an elemental being capable of shifting between her Earth Genasi and Stone Dragon forms. She is written to have served the King and Queen of Dun Therra and an entity known as Onyx.

Description
A calm creature whom sought to parley with the party from Freehearth prior to Kobar's relentless rock attacks. Despite the attacks, the genasi retained her composure and restated her desire for peace and to not engage in war. She had fervently denied that she or her people had stolen any relics from the Giant clan. A lie that had initially been believed by the party, but not by Kobar, who responded by throwing another rock at her.

When it was clear that peace would not be had, her followers turned into elementals forms as Geonid, Gargoyles and Earth Elementals, before she herself turned into a huge dragon of stone, mineral and rock.

She found herself enthralled with the kobold, Pickle, whom she sought as a 'new family member' because of the gemstone he held, before revealing a marking of a jagged crown beneath one of her scales, to show they served the same patron.

Upon her death, Kimberlite turned to gravel, stone and rock. Though rock that pulsated by a beating heart remained and was taken by Dazomar as a trophy.
