The following information comes directly from Silicon Knights' article, Everything You"ve Ever Wanted To Know About Blood Omen: Legacy of Kain,
on their former website. It was last revised by programer, Doug Tooley on January 13, 1997.
Kain
An ambitious young noble whose lust for vengeance overrides his sense of judgment. Kain is resurrected from the dead by the Necromancer Mortanius, for whom he must perform a task of great importance, although what and why it is not revealed to him. Kain's quest leads him on a torturous journey of self- discovery as his curse of vampirism takes irrevocable hold on his soul. The once righteous Kain must slaughter the innocent to survive. As all vampires know - the blood is the life...
Ariel
Ariel was the last incarnation of "Balance". Her magic influenced the regulation of the other magic in Nosgoth. Her prowess in magic and enchantment rivaled that of her beauty, and it was these factors which Nupraptor the Mentalist loved her for. Unfortunately, their love was short lived. The Dark Entity exercised its power and had Ariel murdered at the hands of Mortanius. Now, Ariel is a disembodied spirit "tied" to the Pillars, which she haunts, trying to find someone who will carry out her duties.
Nupraptor
A magician of phenomenal mental and psychic ability, Nupraptor is hypersensitive to peoples' emotions and thoughts. This constant exposure has made him extremely unstable - prone to rash action and sometimes unpredictable and illogical decision making. He is a passionate man, however, and very loyal to those who are special to him. And so it was with Ariel, the original Balance wizard. When Nupraptor discovers that Mortanius, under the malevolent control of the Dark Entity, Hash'ak'gik, has murdered Ariel, he goes over the edge. He vows vengeance upon Mortanius and the fates that have caused this event, and turns his powerful magic to bear on the other members of the Circle of Nine. All across Nosgoth, the minds of the sensitive and intellectual are blasted by relentless waves of hatred. There is no stopping the assault. When the enchantment ends, the entire Circle is quite insane, some raving like madmen, others maliciously in control of their actions... And now, Nosgoth is at their mercy.
Malek
Malek, fanatical warrior-priest of the Sarafan, is Ward of the Circle. He is the defender and paladin to the Circle of Nine, and as so, has vowed allegiance to their protection. Long ago, his inaction allowed several members of the Circle to be murdered by a vicious vampire; and for his crime his soul was fused to the metal of his own armor, which he has inhabited ever since, and will do for eternity. In "life", Malek was known as a ruthless and cold blooded murderer by enemy generals and, particularly, by the vampires who he and his Sarafan cohorts hunted relentlessly. Vampire purges continued under Malek's direction for hundreds of years. In "unlife", Malek stands defiant in battered rune-covered armor, his helmet's plume braided from the bloodied scalps of his many victims. Purged of his humanity by the Circle's sorcery, Malek's hate has been entirely focused on exacting revenge upon the vampire that caused him to be damned for eternity.
Moebius
Moebius is an intensely devious and conniving sorceror. Not many of the Circle trust him, despite the fact that he has maintained his post for many years. His power stems from his control over time travel, and its use in forecasting history. He constantly abuses this power to further his own plans and situation. In the Nosgoth before the Decline, Moebius passed himself off as a wise hermit called "The Oracle" giving benevolent and kind advice to anyone who sought it. Now, after his mind has been tainted by Nupraptor's magic, he causes trouble and torment by predicting omens and horrific events, exploiting them to his own ends.
Mortanius
Mortanius is an ancient sorcerer skilled in the arts of manipulating death. His power has accumulated over the centuries, arguably making him the most potent wizard in all of Nosgoth. His power is tempered with mercy and judgment, however, since he is one of the Circle of Nine ("the Protectors of Hope") - the magicians whose magic preserve the order of magical power in the world. The toils of his magical practices with the dead have made Mortanius little more than a skin and bone husk whose fragility belies his ultimate power.
Bane
Bane is a wizard of Nature. He manipulates the behavior of life and the elements. Through his magic he can change the nature of life itself, animating plants and influencing animals, creating new and weird life forms for his own purposes. The weather itself is at his behest. Bane is dressed in the trappings of a priest of nature - somewhat druidic in essence. Animal skins and hides clothe his body, a deer skull functions as a hat.
Dejoule
Dejoule is a woman of duplicity. Her field of magical specialty is the harnessing and manipulation of energy. This practice has, over the years, altered her physical makeup somewhat. Her body glows with an intense blue light, constantly caressed by tongues of flickering energy. This magical aura has an insidious effect on anybody standing nearby - sapping their energy and blistering their skin, sterilizing cells, etc. Because of this, Dejoule wears a heavy robe lined with insulating fabric which contains her magic. When forced to fight, she'll rip her robe off and let the energy shine through... In this form, she is nothing more than a glowing humanoid female shape, with sparks and arcs of energy whipping around her.
Anarcrothe
Anarcrothe the Alchemist is a tinkerer. He fools around with chemicals, alien substances and strange machinery. He concocts, explores, experiments, and dabbles with forces he only partially understands. Long ago, he became scarred in an accident resulting in one of his more ambitious experiments. The left side of his face was burned away by acidic energies, melding skin and bone in an unsightly writhing tangle. This mutilation he keeps hidden beneath the hood of his robes, so that only the unscarred side of his face is visible. He wears robes of dark, imperial purple, embroidered with the arcane symbology of his craft.
Azimuth - The Planer
Azimuth is an explorer of alien realms. Her magic opens portals and doorways to other dimensions, allowing the creatures within to escape... After the insanity struck, her magic was left intact, but her mind was blasted into obscurity. She is now a raving lunatic that revels in the pain and misfortune of others. The magic she indiscriminately conjures has left numerous cities at the mercy of inhuman demons and creatures that delight in spreading pain. In many ways, Azimuth is an analogy to Nero, who played a fiddle while Rome burned... She revels in the destruction she has wrought with sadistic glee, a trait that was present even before she was driven insane by Nupraptor's magic.
Vorador
Vorador is a proud, arrogant and long lived vampire. He has lived since ancient times, and seen the world grow from being young and vibrant to sour and corrupt. He has feasted upon the teeming human cattle of Nosgoth and learned everything there is to know about the world, reading his victims thoughts as he preyed upon their blood. The great vampire purges, brought to the world by the Sarafan, caused much suffering to Vorador. The Sarafan murdered his friends, lovers, and his vampire children and gave him a valid reason to hate the living. He fought back once, destroying part of the Circle who supported the Sarafan, but it was not enough. The purges eventually drove him into hiding, and so he became lost to the world of Nosgoth.
Elzevir - The Dollmaker
The "Dollmaker" is a magician of little note and unknown origin. His sphere of power, if you will, is the soul of mankind. He is a collector of souls, and in particular he covets King Ottmar's daughter. His mode of magic involves making an effigy of his target person, and then attaching a personal item to it - in the case of the king's daughter, it is a lock of hair. This enabled him to target his enchantments on her, and draw her soul into the effigy. With the effigies he is able to exert power of the person in whose likeness it is carved... Over the years, the Dollmaker has collected many and varied souls for his own twisted reasons.
The Oracle of Nosgoth
From all across Nosgoth, people seek audience with the Oracle of Nosgoth. He is said to have knowledge of past and future, and many seek to find answers to their questions from him. Indeed, he is a wise and benevolent man, proficient in the arts of divination and prophecy. Pilgrims must first find him in his mountain home, and conquer the pitfalls of the labyrinths behind which he hides, and even then, he might not be there. The Oracle is a wise and mysterious man - and works in devious ways...
King Ottmar, the Lion of Willendorf
King Ottmar is a valiant warrior and wise ruler. His armies have united most of Nosgoth and is the only thing which is halfway capable of stopping the advancing Legions of the Nemesis. Unfortunately, Ottmar is melancholic. His faith in his ability to lead and fight has been undermined by the abduction of his daughter's soul. Until his daughter's soul is returned to her body, the future of Nosgoth is grim indeed. Ottmar's court is open to everybody - anyone of his domain is free to enter and converse with the king. He is willing to allow anyone to attempt to retrieve his daughter's soul.
William the Just / The Nemesis
In a previous timeline, William the Just was exactly as his title suggested. A kind, fair and just ruler. Through the insidious designs of Moebius, the Time Streamer, William has become a sadistic despot and tyrant, vying for global domination and the slavery of right thinking folk. For forty years, William conspires with Moebius, creating a fanatically loyal and ruthless army that crushes all in its path, including the Last Hope of Nosgoth, the Lion of Willendorf himself - King Ottmar. William, now known as the Nemesis, tortures and executes those who oppose him. Beheading, disembowelling, impaling peasants and warriors alike in their very own villages. The Nemesis brings with him death and strife, pain and misery, and it will never end...
The Legions of the Nemesis
An ancient seer once prophesied the march of an enormous army that would lay waste to the last havens of peace in Nosgoth and bring about the end of civilization. The seer said little of its origin, but noted that it would gather in the wastes of northern Nosgoth, and crush all who opposes its expansion, and that the people would name it the Legion of the Nemesis. The prophesy foretold rape and torture, death and destruction on cataclysmic levels, and that it cannot be stopped. The peaceful pastoral land of Nosgoth WILL be massacred.
