Uthex Kathiasas
Uthex Kathiasas (? - 6521 Second Era) was a highly regarded Loremaster during the Wars of Dominion in the ICE Age history. As a Loremaster of Karilon, he was most likely High Elven. Uthex was one of the greatest researchers of his time, focused on finding ways of fighting the Dark Gods and the most powerful forces of Unlife. Seduced by The Dark Path, Uthex fell to ever darker magics, eventually working with forging extra-planar entities. These were all named in Iruaric, but were also known by other names, implying their origin in Lord of Essaence experiments. While this concept is esoteric, it still exists in modern demonology, as verlok demons are speculated to have begun the same way.
Uthex was killed by his fellows in 6521 Second Era, the same year the kingdom immediately to the south was crushed by the Ordainer Kharuugh, serving the dark conqueror Lorgalis who was a former servant of Kadaena. While these events never happened in modern Elanthian history, much of The Broken Lands would be considered non-canonical in Shadow World. A monastery of Kai was founded to guard the portal, so servants of the Unlife would not be able to return. Eventually, these monks were corrupted by the evil texts, transforming themselves into liches. The hooded figures regained control of the gateway, and a Sheruvian Monastery was constructed a few years later.
Behind The Scenes
Sage Uthex was retconned to be a member of the Order of Lorekeepers for the release of Miracle (Spell 350) in 5107 Modern Era. The Broken Lands was treated as the surface of Lornon for the story, but it was originally written to be another plane of existence. These are not necessarily self-contradictory possibilities, as there was a source book that said the Lord of Essaence war began when Kadaena was performing extreme planar experiments on Lornon, forming a coexistent dual of it on an artificial prison plane of existence that was much more habitable than the actual moon. It was infested with various extra-planar entities over the millennia, which is consistent with The Broken Lands. There was supposed to only be one surviving portal to that forgotten place, sealed by the Lords of Liabo.
The surrounding hills were intended as an idyllic contrast to the dark struggle being waged in the mountain, which was due to the impossibility of destroying his foul experiments. The monks would have been fighting the hooded figures for centuries, who implicitly were probably being reincarnated by the crystal dome. Incarnating spirit to corporeal being is the distinguishing power of Lorminstra, which is the most plausible meaning of "spirit born of death." That Uthex was incarnating extra-planar beings from pure energy implies his work could have been twisted toward fashioning demons and dark gods. The Shar story line would later refer to the Broken Lands as "The Arkati Workshop", part of her quest to ascend herself to godhood.
