Lore

The Lore of Apex Legends is connected to the larger Titanfall universe.

It is set a few years after the end of the Frontier War, the conflict featured heavily in both Titanfall 1 and 2.

Background
"The Frontier War is over. After decades of conflict between the IMC and the militia founded to fight them, the region of space known as the Frontier can finally see peace.

But liberation can come at a cost: the Frontier worlds were left barren by the war, and promised aid dwindled to nothing. With no way to support themselves, those who remained had no choice but to leave their homes. The brave relocated to the Outlands.

A remote cluster of planets on the fringes of the Frontier, the Outlands are untouched by war and teeming with resources and opportunity. But life is cheap here, and danger lurks around every corner. Its pioneers, explorers, and outlaws used to spend their lives locked in an endless power struggle – now, they settle their differences in the Apex Games, a bloodsport where Legends from all corners of the Frontier compete for money, fame, and glory."

Summary
Apex Legends is focused on the stories of the various legends that participate in the Apex Games, a highly popular, televised blood sport that is owned by the mysterious Mercenary Syndicate and managed by their Apex Games Commission headed by Kuben Blisk.

The Apex Games were initially hosted on Kings Canyon, an island located on the planet Solace. Construction of the arena for the games commenced some time in 2727 and was finished a year after, after which time the games presumably started. The arena at Kings Canyon has been used for 124 seasons, until an attack on the island's Repulsor Tower by Crypto allowed the entry of wildlife, resulting in a devastated arena. The match, then in-progress, was halted and the legends evacuated. The Syndicate suspended the games after the attack and proceeded to make various modifications to the arena in order to increase viewership and contain the wildlife that invaded the island. Various disturbances were reported within the arena, following the resumption of the games, which forced the Syndicate to relocate the games to World's Edge, another arena on the planet Talos.

Following this move, a sponsorship was struck up with the "new" Hammond Robotics, one of the companies that used to make up the now-defunct IMC. This coincided with the entry of Forge, a legend sponsored by Hammond Robotics and the introduction of the Planetary Harvester to World's Edge. Before his entry into the games, however, he was assassinated by Revenant. This, alongside the various reported break-ins on Hammond facilities and the fact that Revenant has a vendetta against both the Syndicate and Hammond, Jacob Young and Cheryl Amacci found a way to contain the simulacrum by allowing him to join the games.

The Broken Ghost
After some time, the games eventually returned to Kings Canyon, but an underground explosion triggered by Loba Andrade, a highly-skilled thief masquerading as a high-society socialite, destroyed a significant part of the island, including Skulltown and Thunderdome. Bangalore hurriedly apprehended Loba, but Syndicate PR Head, Jacob Young, alongside Hammond Robotics Legal Head, Cheryl Amacci, arrived and afterwards announced Loba as the newest Apex Legend. This gave her an opportunity to begin her quest for The Broken Ghost. More specifically, for the pieces of it scattered across the Shadowfall version of Kings Canyon. She mentioned that Revenant cannot find out about their plans. However, Crypto's drone was hacked by Revenant. Accusations of the supposed mole were thrown back and forth between Crypto and Caustic ending with the "A. Smartypants" taking the blame as the whistleblower. As the real mole was able to avoid blame and keep trust with the group from the earlier incident, Gibraltar confronted the real traitor, Caustic, revealing the reason for him to lie and deceive the group, is that he has "skeletons best kept buried" — but most importantly, to keep Wattson away from Crypto. Meanwhile, Revenant and Loba came to an understanding, with him despising his unending existence; and her wanting to kill him. Revenant expressed his intention of wanting to help Loba find his "source code", the only organic part of his remaining, so she can kill him. Together, the Legends assembled all nine pieces, revealed to be the head of the Frontier War-era simulacrum Ash, a pilot that used to work for the "Apex Predators".

Eventually, Loba found Revenant's source code in an underground vault on the planet Olympus. However, instead of terminating it or giving it to Revenant, she sent it through a phase runner, implied to take it to Gridiron, as a way to take away what Revenant wants, which is his death. Learning this, Revenant swore revenge, and plans to take away what Loba may eventually love with all her heart, even if it means waiting for it to come.

Meanwhile, Crypto decided to let Wattson knows about his real identity, which helps mend their relationship.

The First Ship
After Ash's head was recovered and placed onto her body, she was delivered to Hammond Robotics, who after extracting some code from her memory banks, released her. She was soon discovered by Pathfinder in a dumpster, without any knowledge except for her name. Pathfinder takes her to the warehouse he woke up in and they live together in Solace City. Eventually, a visit from Rampart accidentally triggers Ash's memories, which then alerts the attention of Blisk. After all the Legends leave and Ash is alone, Blisk comes to the warehouse. Ash prepares to fight but Blisk explains he was not trying to kill her. He then tells her an old friend of hers is back. Ash runs off with Blisk and leaves a note behind for Pathfinder, thanking him for his help.

Family Portrait
The games soon expanded to Olympus, and using the occasional offtime, Lifeline, Gibraltar, and Octane tried to boot up a century-old MRVN to cheer Pathfinder up; to do that, they need to contact Darion Che, Lifeline's father. Thus, the four of them went to a Chevrex charity event, in which Lifeline have an uneasy catch up with her family while Gibraltar had his own meeting with his ex-boyfriend, Nik. The gala was interrupted by a group of mercenaries who are trying to gain control of Psamathe from the Syndicate, but was resolved with the help of the Legends. Afterwards, Darion gives Lifeline the battery they asked for. Unbeknownst to the Legends (except Octane and a recording D.O.C. drone), the mercenaries were actually hired by Eduardo Silva, Octane's father...

The battery eventually restore the old MRVN's functionality, providing enough clue for Pathfinder to find out not just about the backstories of the Legends, but also how his creation is tied to the Outland Energy Crisis and the project that stopped it. Specifically, he was created by the Project Iris' scientists in the Year 2658 to refine Branthium, but on the day they managed to refined their first batch, the group was betrayed by one of their own in an attempt to steal Branthium for some unknown party. In order to ensure Branthium were delivered to everyone in Outlands while keeping it out of the hands of the unknown party, the scientists triggered the Phase Runner self-destruct sequence, leading to the death of his creators, the appearance of Branthium through out Outlands, and Pathfinder on Solace, disabled and without the memory of his past.

Armageddon
As Outlands stepped into 2734, the Syndicate managed to negotiate with the new warlord of Salvo, bringing it into Syndicate Space; Salvo also sent their repsentative, Fuse, into Apex Games. However, During Fuse's welcoming ceremony, Maggie hacked into Fuse's ship and caused it to fire on the crowd, as well as destroyed the northern mountain range of Kings Canyon, before publicly demanded the Legends bring her Fuse's other arm. Fuse, Lifeline, and Bloodhound went to confront her. After refusing Maggie's request to return to Salvo and left her hideout, Maggie hijacked control of the Games and caused Ring Flares and numerous quirks throughout the matches. Having enough, Fuse tried to confront her, but she managed to shoot him down while he was on his way. Confronting each other on the ground, Fuse reaffirmed his decision to stay in Apex Games, before both him and Maggie launched their attacks at each other, resulting in an explosion that sent both dangling above the streets of a city. Disappointed with her loss in both her fight and her friend, Maggie let go and fell to her death.
