Background: Xereth Yorn, the malevolent head of the Order of Ket'Thal, epitomizes the darkest aspects of necromancy. He has a tenuous relationship with Nathrak Ultar and the Sisters of the Void. While he begrudgingly acknowledges Nathrak as the current ruler of Klethos, his allegiance lies solely with the Order of Ket'Thal and his undying master, Ket'Thal. Xereth is a being devoid of empathy, driven by an insatiable obsession with necromancy and the power of undeath. His loyalty to Ket'Thal fuels his ambition to one day see his master restored to his former seat of power in Klethos.

Xereth's appearance is as dark as his soul, with hollow eyes that seem to pierce through the living and skin that appears almost cadaverous. He exudes an aura of death, a constant reminder of his preference for the company of the undead over humans or any other living beings. This preference extends to his leadership style; he surrounds himself with reanimated servants and spectral advisors, finding solace and loyalty in their unwavering obedience.

As the head of the Order of Ket'Thal, Xereth is ruthless. He maintains an iron grip on his followers, consistently rooting out the weak and uncommitted with a brutal efficiency. The Order under his command is a tightly knit group of necromancers, each as devoted to the dark arts as he is, though none as powerful. He demands absolute loyalty and dedication, ensuring that only those who truly embrace the path of undeath remain within the Order.

Xereth's relationship with Nathrak Ultar is fraught with tension. Although he recognizes Nathrak's authority in Klethos, he views him as a necessary obstacle rather than a true leader. Xereth's ultimate goal is to resurrect Ket'Thal and restore him to power, a vision that often puts him at odds with Nathrak's leadership and the goals of the Sisters of the Void. Despite this, Xereth is shrewd enough to maintain a façade of cooperation, understanding that open conflict would weaken their collective power.

Xereth's singular focus on necromancy and undeath has made him an expert in the field. His knowledge of the dark arts is unparalleled, and he is constantly seeking new ways to enhance his power and that of the Order. His research is unending, delving into ancient tomes and forbidden rituals to uncover secrets that will aid in the return of Ket'Thal.

In the bleak and cursed land of Klethos, Xereth Yorn stands as a dark pillar of malevolent ambition. His unwavering dedication to the Order of Ket'Thal and the resurrection of his master defines his existence, making him a formidable and feared figure among the necromancers of Zyricus.
