Malice and Spite

Part 0: Prologue

The Traveler came and sparked a golden age for humanity. Humanity prospered and thrived but it didn't last long. Soon, the dark came and destroyed everything. The last city was completely taken over and most of the ones who survived fled to the tower. As the Traveler died it used it's light to make guardians, their ghost, and their weapons to fight off the dark. Guardians are regarded to be humanity's last hope. Warriors wielding the light of the Traveler to fight off the creatures of the darkness. Though some think otherwise.

When the darkness came some people refused to leave the city. The dug in and hid from the creatures, learning to live with them and avoid them.
Others chose to flee to the tower where the speaker and Guardians found there home between missions. In an attempt to take control of themselves the people divided into three main factions, Future War Cult, New Monarchy, and Dead Orbit. Each having it's own set of views.
Those who strayed from the tower were usually driven to madness or chose some obscure belief to keep them sane. Many worshiped the traveler and prayed it would save them while others prayed for it's power. Some thought the traveler was evil and it's Guardians would kill them all. Some chose to simply learn how to survive, taking whatever they could scavenge and adapting to the harsh way of life of living in the wastelands of Earth.
Even some Guardians strayed from the path of saving humanity and dove into such matters of experimenting of life forms, darkness, light, or human alike. Some went rouge and killed other Guardians and smashing there ghost, making cloaks out of there victims armor.

The Guardians we follow are exiled for experimenting with the darkness in an attempt to harness it after The Taken King had been slain. After all, if Oryx could take from the Darkness and slay gods, who's to say Guardians couldn't.
