Galaxity, capital of the Terran Empire in the 28th century. Valerian and Laureline are agents who protect mankind from rogue time travellers. Now they are sent to New York in 1986 to intercept Galaxity’s worst megalomaniac, Xombul—except that in 1986, the world is in ruins and New York is about to be swallowed by the ocean. The two agents must navigate the shifting waters of the past to make sure that the future will exist.

Valerian and Laureline are exploring Syrte, capital planet of a system of 1,000 worlds. Their mission is to discover whether the Syrtians could present a danger to Earth. What they find is a decaying empire led by decadent aristocrats, a population ripe for revolution, and a mysterious caste of masked wise men who discreetly pull the strings from hidden fortresses. Swept up by the winds of history, the agents of Earth will have to choose a side…

When a rogue planet threatens a new Human colony, Valerian and Laureline are sent to investigate and discover a barren, rocky surface… and a whole world beneath it! The people who live inside Zahir have never seen the stars. Divided along gender lines, torn by a senseless and bloody war, they are unaware that their planet is hurtling towards disaster. To stop it, the two agents of Galaxity will have to infiltrate both sides and force a reconciliation.

Technorog is a planet essential to the economy of the Terran empire. For 200 years, it has been a centre of industry, research and agriculture. Suddenly, the indigenous population—believed long extinct—comes back to the planet they know as Alflolol. Earth’s laws are strict: They must be allowed back on their ancestral grounds. But when Valerian and Laureline are assigned to facilitate their “reinsertion,” they see the difference between the letter of the law and its spirit...

Valerian and Laureline’s ship has crash-landed on an uncharted planetoid. The two castaways quickly discover a vast ship cemetery, leading them to believe that their arrival was not an accident. Before long, they make contact with a population whose sole purpose seems to be to gather and produce food for a mysterious “Master.” The Terran agents aren’t going to be turned into slaves easily, but the Master enforces his will through his terrible agents: the Birds of Madness...

Point Central is a multicultural space station that serves as a sort of United Nations to the galaxy. Tasked with protecting the new ambassador from Earth, Valerian is kidnapped alongside his charge in a lightning commando attack. It’s up to Laureline to do all the heavy lifting and slog through the seedy bowels of the station as she tries to locate and rescue them—and figure out who kidnapped them and why.

Valerian, shot to death in an Indian fortress. Valerian, dead in 19th century London. Valerian, gunned down in San Francisco’s Chinatown… And Laureline, paired up with an unpleasantly arrogant historian from Galaxity, forced to witness every demise of the man she loves on a succession of re-enacted pieces of human history. A very strange case that will take the two spatio-temporal agents to the limits of their endurance as they hunt down the mysterious architect of the false Earths….

Every 100 years or so, the infertile people of Simlanne send their champions to the sacred island of Filene, where the best among them, chosen via a series of tests, will find and bring back the next generation. This cycle, though, the local heroes seem to fail repeatedly, and the aging Simlannians have sent for heroes from other worlds. Valerian, chosen to represent Earth, will have to overcome the tests and his competitors in a dangerous odyssey…

Our two spatio-temporal agents are on a new mission, but this time the duo is split up. While Laureline flies solo from planet to planet, on the trail of arms dealers and forbidden technologies, Valerian is on 20th century Earth, teamed up with the eccentric Mr Albert. And he, too, is hunting down technologies incompatible with the era. What is the link between the two cases, separated as they are by centuries and light-years?

The two Galaxity agents’ investigation into the elemental forces appearing on Earth continues. While Laureline, dogged and efficient, follows a promising lead somewhere in outer space, Valerian is struggling to unravel the mysterious events plaguing our 20th century. Demonstrations of fantastic phenomena follow in quick succession, pushing poor Valerian to his limits. And matters will have to be settled simultaneously in New York and on an asteroid on the edge of the galaxy to save our world...

The head of Galaxity’s Spatio-Temporal Service himself has joined Valerian and Laureline at Inverloch Castle. There, among various human and alien allies, he explains to them the threat that looms over Earth: all of the recent incidents, all those important people gone mad and threatening to bring about the apocalypse... All of that is due to the malicious influence of the mysterious planet Hypsis. But Hypsis is a world that moves from system to system – it’ll need to be pinpointed first...

On an interstellar cruise ships, a mysterious individual in full environmental suit is working hard to get to Earth. On Earth, meanwhile, another person in a spacesuit is exploring a nuclear reactor on behalf of its owners. That second man is Valerian, and since the disappearance of Galaxity, he’s been forced to make a living by putting his advanced knowledge and equipment to good use. But what he’s discovered insidethe plant is extremely worrisome...

Valerian and Laureline take a break from adventuring and go on a cruise, but Valerian feels uncomfortable among the idle and the powerful. He’s not bored for long, though, because when a quartet of mercenaries board the cruise ship to kidnap the son of the Caliph of Iksaladam, they end up taking Laureline as well. With the almighty Caliph offering a massive reward for his son’s return, Valerian’s quest to rescue his girl is suddenly hindered by every bounty hunter in the galaxy…

Running away with the unhappy heir to the galaxy’s biggest fortune, even if it’s because he wants it, is bound to cause some problems. On the lam with the Caliphette of Iksaladam, Valerian and Laureline are relentlessly pursued by the Quatuor Mortis, who are still after the enormous reward offered for the child’s safe return. Stranded among the Asteroids of Shimballil, they must evade the hunters, recover their ship, dodge profiteers and traitors … and decide what to do with the little brat!

The (false?) gods of Hypsis are once again interfering with Human history. Tired of their lower status among their peers, the trinity in charge of planet Earth opens communications with megacorporation Vivaxis at the end of the 20th century – an occurrence Valerian and Laureline’s allies report to the two ex-agents. But to what end did the Hypsians initiate such a contact? And who is the mysterious Sat who, from the depths of Point Central, also endeavours to meddle with Human affairs?

Somewhere at the edge of known space is the Great Void. That inscrutable, shapeless, ever-changing place is where the expanding universe springs forth, where new planets and new life forms are created. It’s also, according to the gods of Hypsis, the place where Galaxity’s Earth was sent and is being kept prisoner. Valerian and Laureline begin a discreet investigation, but it doesn’t take long before they start finding obstacles in their path, placed by the rulers of Rubanis – and their mysterious master...

The expedition into the heart of the Great Void is launched, and Valerian and Laureline are on it. But in no time they’re already facing the mysterious force that threatens the entire galaxy: the Wolochs, gigantic sentient monoliths dead set on destroying any civilisation that might stand in the way of their domination. Our two Human agents can’t hope to stop the Order of the Stones by themselves, but fortunately, they still have allies...

The evil hordes of the Wolochs are rampaging through space, and everywhere death and destruction follow. But despite the despair of some and the betrayal of others, Valerian, Laureline and a few other brave souls are resisting. They’re hoping to use a mysterious artefact, the Time Opener, to banish the stones and bring back Earth. But what price must they pay to do so? And what sort of Earth will they get back if they succeed?

Even though Valerian and Laureline’s adventures have come to an end, there are still many chapters that haven’t been told yet. Simple episodes, post-scriptums to their main stories, moments of their lives seen through the eyes of their friends, their allies, or even their enemies. Here’s a collection of vignettes that will cast a new light – sometimes funny, sometimes touching – on the saga of our heroes.

After the events of The Time Opener, Valerian and Laureline reverted to childhood, and are now living with Mr Albert on 21st century Earth. But in a universe where time travel is a reality, words like ‘after’ or even ‘now’ can be somewhat … hazy, and elsewhere, in other times, our young but nonetheless adult agents are still working tirelessly to maintain a galactic peace threatened as always by greed and the thirst for power.
