we aren't guardians of earth, we are guardians of the travel. we were made into weapons to defend the traveler.

Symbiotic relationship. Traveler terraforms planets in exchange it turns our dead into its personal bodyguards and attack dogs.

By the way it acted with the Ammonites and the Leviathan of Fundament, it looks that way. It seeks to enrich civilizations. Why it stayed to defend us is unknown, but lord knows it probably stayed asleep because of the damn Darkness. It's like a -blam!-ing homing beacon. "HEY ILLUMINATI COME GET ME!!"

He's held hostage by Rasputin. If he attempts to leave than Rasputin will unleash hell. Rasputin knows that if the traveler leaves than we'll plunge into further darkness and may never come out if it.

Pretty sure Void is the 'darkness'. 'Void Light' as its called is oxymoronical, for lack of better term. When we are referred to as food for the Traveler, its a metaphor. The Traveler 'hungers' for the interaction it gets from Humans, and gives Humans the powers they have to protect themselves, because the Traveler sees good in them, I think. If the Traveler didn't offer the same thing to the Fallen, then the Traveler maybe didn't like them quite as much. The Fallen are a bit more hierarchical, and abusive even. They seem to value strength above all else, like much of the 'darker' races. Humans are supposed to be more noble. I think Calus has some truthful information he wants to share with us, where as the Speaker basically had 'white lies'. The Speaker really didn't even communicate with the Traveler, just spoke on its behalf, to give people a hopeful message. I think there is some debate about 'midnight exigent' and how Rasputin shot down the Traveler to prevent its escape. It may be precisely what happened, but I'm not 100% sure, there's some dispute and I don't remember the details.

I dont thinks its evil but its not that good either it just made guardians to protect itself and was forced to stay on earth cause the darkness surrounded it

The Traveler didn't make Fallen Guardians. Remember that the Guardians were only created following the Collapse. We can assume because it wasn't damaged when it came to Earth that the Traveler left the Fallen before their collapse. We're the last resort of a crippled Traveler fighting back against the Darkness. It's implied humanity is the first race the Traveler has ever done this with. I think you're on to something with the Traveler trying to flee during the Collapse. This was hinted at in Destiny 1. There was a grimoire card that revealed Rasputin had orders to cripple the Traveler if it tried to abandon humanity. And we still don't know whether it was the Darkness or Rasputin that broke the Shard off the Traveler. As for the fourth subclass rumour, I really don't think it's darkness. That wasn't even part of the original rumour. The rumour comes from a line Ikora says in the Tower, where she wonders if there's a fourth type of Light.

We really do not know what the Traveler did with other civilizations. The only real record is from Fundament where the Traveler remained until the Ammonites had been totally destroyed before leaving. A flavour text on a weapon is meaningless without context for the Fallen. Secondly there is no evidence that the Traveler made Fallen Guardians. The reason the Traveler remained, and yes we know it chose to stay, was because it had a vision when approaching our solar system, a vision that filled it with hope. Lastly on the nature of the Traveler we have the Books of Sorrow [quote]++We live on the edge of a war— —a war between Formless and Form++ ++between the Deep and the Sky— ++MY EYES ARE WIDE, MY GAZE IS LONG++ —Across the universe, as far as I see++ ++the Sky works to charge its fires— —and the Deep drowns the ash++ —Sky builds gentle places, safe for life++ ++Beloved Fundament, refuge of trillions— —The Sky treasures this rich place++[/quote] and [quote]++The Sky builds new life++ —Against the onset of ruin— ++Towards a gentle world++ —The Deep embraces death— ++Saying: this is inevitable and right++ —I exist as hungry ruin— ++TURN BACK FROM THE WORLD-KILLING WAY++ ++OR YOU WILL LIVE AS DEATH AND DEVASTATION++ —The Sky is the harder way.

The last warning became true of the Krill, they became death and devastation under the Deep/Darkness as the Hive.

If you ask me The Traveler is manipulating others to do its bidding and will eventually backstab the player becomming some sort of boss fight

The traveler is actually Luke Smith, he'll be the raid boss in Destiny 666.

Well in the first cinematic for D1, it shows the darkness literally trapped the Traveler here. It surrounded the solar system.

The fallen were never made into guardians. And we have the inner monologue of the traveler so we know it chose to stay and fight. We also have an eye witness account in the form of Rasputin who literally says the traveler saved all of humanity on its own while he sat and did nothing.
