It then awakened, either of its own accord or as a result of the species' actions, and proceeded to terraform the planet and bestow paracausal gifts to its discoverers, much as it would later do with many other species. In one of her messages to the Guardian through Sloane, Ahsa makes reference to ' two halves of a whole, long divided,' which in context seems to suggest that the Traveler and the Veil were once part of a single entity, or at least share a common origin.Īs revealed by Ahsa, billions of years ago the Traveler lay dormant and half-buried on a desolate planet, where it was discovered by a humanoid species. The origins of the Traveler are unknown, although it is known to have existed for billions of years. It would seem then that its defense of humanity was an extraordinary act under dire circumstances. In the past, whenever its work was finished, it would simply leave without fanfare. The Traveler seems to be motivated by pure altruism it has never wished to be worshipped as a god, nor has it made its presence known any more than necessary to cultivate a civilization. The Traveler hovering in place over the Last City Fenchurch Everis claims to have been inside the Traveler, but no one has been able to confirm the veracity of his story.

Another Ghost named Peach was dismissive of this description, contending that neither she nor Balthazar can remember the time within the Traveler. The Ghost Balthazar claimed that Ghosts originate within the Womb, a place inside the Traveler described as a 'cosmos inside a bottle' or an 'infinite space enclosed within a celestial egg', where trillions of star-like souls orbit each other in a complex weave. The interior workings of the Traveler remain a mystery. Its outer shell is made of lead, neutronium and 'electroweak matter', the latter based on a fundamental force that hasn't existed since the dawn of time. It is a source of Light, though not the only source in the universe. The Traveler is an ancient and immensely powerful machine entity, the source of Ghosts and the Light-based powers of the Guardians.
