[1] The Parallax entity is a space parasite that is the embodiment of fear that was imprisoned within the Central Power Battery on Oa.

[2] Thaal Sinestro, at the time the universe's greatest Green Lantern, was sent to Earth by Supernova in a plot to erase Guy Gardner from history.

Arkillo, a large and muscular vicious alien, is enslaving all the Qwardian Weaponers and forcing them to continuously build new yellow rings which are programmed to breach the barrier between the antimatter and matter universes to find and recruit new ring-wielders.

Arkillo also serves as the Sinestro Corps' drill sergeant, similar to Kilowog's role in the GLC.

[9] During this time, the Sinestro Corps attempted to recruit Batman, known even to some alien races for his formidable ability to instill fear in others.

[10] It was revealed that after untold millennia, the Weaponers of Qward, Ranx the Sentient City, the Children of the White Lobe, and the Empire of Tears will rise united against the Green Lantern Corps.

Hal and Guy found several Green Lanterns, all of whom were assumed to have been killed during the Emerald Twilight saga, and the Manhunters' new grandmaster Hank Henshaw, the Cyborg Superman.

[12] The Book of Oa has a forbidden chapter on cosmic prophecies, which includes the following: A face of metal and flesh shall speak of the secrets of the 52.

There he amasses an army, the Sinestro Corps, that he selects based upon their ability to "inspire great fear".

During the assault on Oa, the Sinestro Corps manages to inflict heavy casualties and free Superman-Prime and the Cyborg Superman from their imprisonment.

Hal manages to free Kyle from Parallax before the entity is imprisoned in their power batteries by Ganthet and Sayd.

[17] After John and Guy arrive, the former Guardians reveal to them the prophecy of the "Blackest Night", seen in Green Lantern vol.

One of the Guardians sacrifices himself to send Superman-Prime to an alternate universe, while Hal and Kyle subdue and arrest Sinestro in Coast City.

[20] Meanwhile, Mongul (who had since obtained a yellow ring in the aftermath of the war) begins his quest to take command of the Sinestro Corps in their namesake's absence.

Their rescue attempt is temporarily spoiled by an attack from Atrocitus and his newly formed Red Lantern Corps.

[21] Sinestro is abducted by Atrocitus' forces and brought to the Red Lantern base planet: Ysmault.

[26] Sinestro's rescue attempt is interrupted by a Black Lantern attack, which he only survives through the arrival of Hal Jordan and Indigo-1, leader of the Indigo Tribe.

[27] When he departs with Hal Jordan's group of light-wielders, he commands his Corps to gather at Korugar and protect it while he is away.

However, as they establish a presence where Oa was once located, Hal Jordan forges a new ring for himself as the rest of the Corps return to this universe.

A Corps member named Strafe mistook a rebel to be Soranik Natu, who has secured Hal safely, though he was killed by Sinestro (this whole sentence makes no sense and I don't have the knowledged to correct it accurately).

The Sinestro Corps then begin capturing people and imprisoning them in Warworld's engine to increase the power of fear.

[44] Before Sinestro attacks him, he discovers too late his powers are decreased due to Soranik rescuing people from being imprisoned and escaping with them.

Hal then uses his energies as a living construct to incinerate the Fear Warlord, apparently destroying Sinestro and Ranx for good.

When recharging their power rings, members of the Sinestro Corps recite the following oath: :In blackest day, in brightest night, As the embodiment of fear which is connected to the yellow light of the Emotional Spectrum, Parallax is revealed to be the emotional entity for the Sinestro Corps.

The Sinestro Corps insignia is based on drawings created by life forms who looked into the mouth of Parallax, and lived to tell the tale.

The Book was eventually destroyed during the rampage of the First Lantern, but its text continued on as the "Lore of Parallax", inscribed directly into Lyssa Drak's skin and mind, and developing further every time a new member was added.

In the "Lantern" arc, Parallax possesses John Stewart and sends yellow power rings to Earth, where they choose Arkham Asylum inmates, such as Man-Bat, Firefly, Bane, Mr.

Freeze, and Poison Ivy, before they are all defeated by Superman and the Green Lantern Corps and depowered by Dr. Emil Hamilton.

[85] In the "Chaos" arc, Lex Luthor employs a security force empowered by yellow power rings until they are defeated and depowered by Booster Gold and Skeets.
