Inspired Lord Kaltaresh (in a long-dead vessel) organized the soldiers who opposed the Nulakesh incursion in 390 Unity (88 YK). Thus, among the Edgewalkers, he is known as "the First."
Kaltaresh is especially powerful and cunning for a du'ulora; he has 24 Hit Dice, and his mental ability scores are Int 20, Wis 23, Cha 21. Two thousand years ago, he was one of the commanders in the battle against the quori who eventually became the kalashtar, and he learned much of the planes during this hunt. He hates the kalashtar and believes that the followers of the Path of Light must be destroyed. However, Kalataresh is one of the few quori of the age who is not actually evil. He does what he must to protect his people, but he is not cruel by nature and he does not savor violence. He is truly concerned with the stability of Eberron and disturbed by the Mourning, believing the fate of the quori to be linked to Eberron.
For now Kaltaresh follows the guidance of the Dreaming Dark, but he could ally with Lady Sharadhuna if she opposes the Devourer. Other quori know of Kaltaresh's aberrant alignment, but so far his personal power and reputation have kept him alive
