Moebius

Moebius is an antagonist character introduced in Blood Omen; one of the insane sorcerers whom the main character must kill in order to progress in the game. Moebius is one of only three characters who makes at least a cameo appearance in every game in the series (the others being Kain and Raziel), and serves as a major antagonist. He is used as a boss character in Blood Omen, but is more frequently used to advance the plot of the games in which he appears. Within the context of the story he has power over time, and his foreknowledge of events allows him to interact with the main characters in a consistent manner despite his chronologically inconsistent appearances. Throughout the series he has been voiced by Richard Doyle. According to bonus features in the games, Moebius was known as "Bridenal" in the early development of the series.

Blood Omen
Moebius is introduced in Blood Omen under the title of "Oracle of Nosgoth". Later he is revealed to be the Guardian of the Pillar of Time; his prophetic ability is based on his power to travel through and observe different time periods. Described as "intensely devious and conniving",[1] Moebius is behind King William the Just's turn to tyranny. Moebius later manipulates Kain through his alter-ego as the Oracle, and through time traveling devices left in Kain's path, into assassinating the King William in the past, before he becomes a threat. Kain's act inspires outrage against vampires among Nosgoth's human majority, which Moebius leads in bloody crusade against vampires. Kain battles and kills Moebius, but by this point Kain is the last surviving vampire in Nosgoth.

Soul Reaver & Soul Reaver 2
In Soul Reaver, Moebius appears to Raziel in the final scene of the game, leading into the events of Soul Reaver 2. Soul Reaver 2 adds new layers to Moebius' character. Over the course of the game he urges Raziel to kill Kain several times from behind a facade of ineffectualness, revealing to Raziel that they serve the same master, the Elder God. As he did with Kain in Blood Omen, Moebius uses time traveling devices to manipulate Raziel, who unwittingly enables the slaying of Janos Audron. At the end of Soul Reaver 2 Moebius almost succeeds in goading Raziel into imprisoning himself in the Soul Reaver.

Moebius is one of few characters in Defiance that interacts with both of the protagonists.
