The story opens with
Adam Strange witnessing the entire planet
Rann lapse into madness due to an attack by the cosmic entity Oblivion. As Strange tries to defend the planet, he is unwillingly transported to Earth, where he gets help from
Firestorm and the
Atom in alerting the
JLA of Oblivion's approach. When Strange debriefs the JLA about the encounter,
Kyle Rayner is shocked to hear the description of Oblivion, because it matches the description of a
supervillain Kyle had created as a child for a story he made during his period of struggling his fear and anger of growing up without a father. The JLA engages Oblivion, who can create cosmic events such as
black holes and
dwarf stars. They are quickly overpowered, so Kyle retreats to gather other heroes to help him. After a warning from the
Spectre that someone close to Kyle would betray him, the Green Lantern asks for assistance from
Oracle, who sends over
Power Girl. Just as she arrives to help, six new Green Lanterns appear, each claiming to be the sole protector of Earth in a different time or universe. They are: • Pel Tavin, the
Emerald Knight, a
Daxamite knight from the 13th century. • Ali Rayner-West,
Green Lightning, a descendant of Kyle and
Wally West who has both a
power ring and super-speed. • Hunter and Forest Rayner, cousins and members of the
Teen Lantern Corps, who are from a world where Kyle's descendants all share his original power ring. •
G.L.7177.6, a reprogrammed
Manhunter android. •
Alexandra DeWitt who, in an alternate timeline, received the last power ring, only for Kyle to be murdered soon after (an inversion of Kyle's story). Kyle splits the group of heroes up to go investigate Oblivion's arrival and rescue the captured JLA, pairing Power Girl with the Emerald Knight, Firestorm with G.L.7177.6, Green Lightning with Adam Strange, and the Atom with the Teen Lanterns. He chooses Alex to be his partner to go and hunt down Oblivion and stop him. In
Green Lantern and the Atom, the Atom and the Teen Lanterns try to figure out who created Oblivion, narrowing down the field to four suspects: the
Scarecrow,
Doctor Psycho,
Professor Ivo, and
Doctor Light, all of whom have no idea who Oblivion is. Back at Kyle's apartment, they find a sketch of a character, Sir Nobleman, who resembles the Emerald Knight in a notebook from Kyle's childhood, suggesting that Oblivion and Pel Tavin were created together. In
Green Lantern and Power Girl, the Emerald Knight and Power Girl locate the JLA on a distant planet, only to find them encapsulated in a yellow crystal. After being unable to break them free, Power Girl realizes that they are not in danger, but rather are being kept safe inside. In
Green Lantern and Adam Strange, Green Lightning and Adam Strange return to Rann only to find it in ruins, not from Oblivion's work, but from the population's madness. They discover the source of the hysteria is a giant green lantern broadcasting a signal that only Rannians can pick up. They conclude a Green Lantern must have constructed the beacon. In
Green Lantern and Firestorm the Nuclear Man, G.L.7177.6 and Firestorm search for the "Omega Option", the only thing capable of stopping Oblivion in Kyle's childhood comics. However, they are unsure if the Omega Option exists. As G.L.7177.6 and Firestorm travel through space, they encounter
Martin Stein, a fire elemental who was one half of the original Firestorm. They eventually discover that the weapon does not exist. In the last team-up book,
Green Lantern and Green Lantern, Kyle and Alex deal with their conflicting emotions over each seeing their long-dead partner as they track down Oblivion. During this, Kyle finds himself mysteriously weakening. They finally find Oblivion on the ruins of
Oa, so they call everyone to rendezvous. As the backup arrives team-by-team, the friends fill each other in on what each team had discovered. Piecing together the clues, Kyle concludes that Pel Tavin must be the traitor that the Spectre warned about. Before the Emerald Knight and Power Girl return, however, Oblivion attacks the heroes, killing Forest. As the Atom and Hunter are about to face the same fate, the missing duo swoops in to save them. Realizing that Pel Tavin was not Oblivion after all, Kyle charges towards the supervillain, only to be transported into his own subconscious. There, he learns that Oblivion was created using the power of the ring and the negative emotions Kyle bottled up after Alex's death and that the new Green Lanterns are equally imagined, each representing a positive aspect of Kyle's subconscious; Alex is an embodiment of Kyle's capability for love, while Tavin represents his courage, Ali represents hope, G.L.7177.6 represents logic, and Hunter and Forest represent imagination. Kyle also realizes that his current weakening state is because of subconsciously sustaining the Circle of Fire's existences with his willpower, and he eventually would die if they are not returned to him. The heroes agree and Kyle absorbs each of them to gain enough power to fight Oblivion, even Alex herself after she and Kyle bid their tearful farewells. Oblivion threatens to destroy everything Kyle loves, starting with
New York City, unless Kyle lets Oblivion take over his mind and therefore the power ring. Kyle threatens suicide to stop Oblivion, but Oblivion reminds Kyle that the JLA would be lost forever. Instead, Kyle lets Oblivion into his mind, where he is overwhelmed by Kyle's positivity. Having rescued the JLA and stopped Oblivion, Kyle tenders his resignation.
Superman,
Wonder Woman and
Batman on the other hand interpret this to be a sign of maturity and responsibility and refuse to accept his resignation. The Spectre, who is hidden, watches this meeting and is proud of his successor. Following the meeting, Kyle is eager to look forward into the future. == Aftermath ==
