Bronislaw Czevak - Notable Opponents: Mammoshad (Daemon, banished) - Also known as the "King of Kings, Enslaver of the Craven Worlds and Keeper of the Vault Abyssal," Mammoshad is a Lord of Change, a Greater Daemon of Tzeentch. Millenia before, Mammoshad was subjected to psychic vivisection by a Dark Mechanicus cult called the Daecropsicum, and its pieces were scattered throughout the galactic East. Following Korban Xarchos' manipulations, one piece of the daemon came into Czevak's possession, only to psychologically and mentally torment him. Recently the daemon was the object of a long-running reactivation project by Korban Xarchos and the Thousand Sons. Mammoshad was banished back into the Warp during its rebirth by Czevak through the use of the Pariah embryo.Valentin Malchankov (Inquisitor, Ordo Hereticus, active) - Malchankov was a member of the reactionary Monodominant Puritan faction of the Inquisition, and an implacable opponent of Czevak, whom he considers a dangerous Heretic and Radical "schismatist." Following a particularly heated argument with Czevak, he publicly vowed to hunt him down. His assets include the Black Ship Divine Thunder.Pavlac (Imperial, Witch Hunter) - Pavlac is a Witch Hunter and probably an Inquisitor of the Ordo Hereticus. He actively campaigned against Czevak and any who support him, condemning other Inquisitors and whole worlds. His status after Czevak's return from the Black Library is unknown.Ahriman (Chaos Space Marine, psyker, active) - Ahriman is the mightiest Chaos Sorcerer of the Thousand Sons Traitor Legion after its daemon Primarch Magnus himself, and perhaps the greatest mortal Sorcerer in the galaxy. He is dedicated to the pursuit of a perfect understanding of Chaos and his patron, the Chaos God Tzeentch. For this reason, Ahriman desires nothing more in existence than to enter the Black Library and learn its myriad secrets. Thanks to information gleaned from torturing Czevak, Ahriman managed to once breach the Webway, but was repelled by the Aeldari. Ahriman was injured by exposure to the Pariah embryo at Melmoth's World. Despite his wounds, Ahriman will never stop in his relentless pursuit of Czevak and all he knows.Korban Xarchos (Chaos Space Marine, psyker, deceased) - Xarchos was a Chaos Sorcerer of the Thousand Sons Traitor Legion, and the Equerry and apprentice to Ahriman. Xarchos commanded the Traitor Frigate Rubrician. A shapeshifter, he was slain after being used by Ahriman as a shield against Czevak's Pariah embryo.Eldrad Ulthran (Aeldari Farseer, psyker) - The strongest living psyker and likely the most powerful member of the leaderless Aeldari race was one of the Farseers who most vocally called for Czevak's death while he was in Aeldari custody. However, by the time the Black Council met for the second time to discuss Czevak's fate, Ulthran was away fighting against the 13th Black Crusade of Abaddon the Despoiler. Had Ulthran been present to judge Czevak, Iqbraesil might not have been able to sway the Council in Czevak's favour against the strength of Ulthran's influence. Ulthran is now a major champion of the new Ynnari religious faction in Aeldari politics.Vespasi-Hann (Aeldari psyker - deceased) - Vespasi-Hann was a Harlequin Shadowseer. Part of the Harlequinade assigned to monitor Czevak's activities after he first travelled to Iyanden, because the Inquisitor was considered by the Aeldari to be an "asset" to be used in their undeclared war against Ahriman and the Thousand Sons. Czevak used the Atlas Infernal to kill the Shadowseer during a confrontation within the Webway.Various Harlequins - A Great Harlequin, a Death Jester and others (active). Injured by Czevak's brandishing of the Atlas Infernal during the encounter that resulted in the death of Vespasi-Hann, they retreated from recapturing or killing him.The Black Council (Aeldari political body, active) - This Aeldari advisory body of Farseers drawn from every major Craftworld has in all likeness condemned Czevak to death as a danger to the Aeldari race, and has additionally tasked the Harlequins (who act as the Black Council's enforcers) with retrieving the Atlas Infernal. However there is dissent in the Council and not all members seek Czevak's death (in particular, Iqbraesil of Iyanden is Czevak's strongest supporter on the Council).
