Prologue:

The Tower, Earth

As a Quite Content Damsel model ship flew into the docking hangar, the blue aura of the transmat appeared on the balcony of the tower. Out of it came a green Exo with glowing purple eyes. Also from it came his small companion, the tiny machine called a ghost.

It was a typical day at the tower. The Exo turned in and collected some bounties to Xander, the frame who monitored all incoming bounties and HVTs. He checked over the bounties and notified the Vanguard and Dead Orbit factions.

Just as the Exo turned around to leave, Xander called to him. "One more thing, Guardian."

"What?"

"The Vanguard leaders request your prescence."

"I'm busted, aren't I?"

"Unknown."

"Great." The Exo mumbled as he walked over to the Cryptarch. He had Master Rahool decrypt the few engrams he had and dismantled them into resources. Then he made his way to the stairs to the Vanguard.

At the base of the stairs, he passed Eris Morn, the girl with three eyes (presumably). She had set up shop at the base of the stairs, with a glowing jar, though nobody knew why on both counts. When the Exo passed her, she stared in his direction.

"Heh, creepy as ever." The exo chuckled silently.

He got to the Vanguard table, and saluted the Vanguard leaders.

"Ikora." He said to the dark-skinned Warlock female. "Cayde." To the Exo Hunter. "Commander Zavala." To the Awoken Titan. "To what do I owe the pleasure?"

"Something big is going down with the Fallen, Hive, and Cabal. Must be big if the Cabal risk fighting us here." Said Cayde.

"There is a massive concentration of all three species in the North American Continent." the commander said grimly as he pointed to the map.

"Maybe they just want a party." Joked the Exo

"I had a scouting fireteam down there." Said Ikora. "They managed to get us a real time view of the area, at the cost of their light." She turned on the holo-map. It showed, well, massive concentrations of all three species fighting what could only be called a war.

Zavala frowned. "We believe they are fighting over something of extreme importance in or under the ruins of the East coast. The Fallen and Cabal are tearing apart what used to be New York City and Washington DC, while the Hive seem to have turned the island of Manhattan into a fortress."

Just then a radio message came into the room. "Hey Zavala! Ya wanna see what a transmat beacon looks like in Central Park?"

"You went into a warzone without permission?!"

"Oh, yeah. Can I have permission?"

"Ah, he learned from the best." Sighed Cayde.

"Hold your ground, Guardian. We're sending a guardian to get you." A concerned Ikora.

The Exo stepped back one pace. "Sooo… guess I'm up."

"Take another guardian with you. You will need a full Fireteam if you get into a tight spot."

"Aye-aye, Commander. Ghost, beam me up!" The Exo transmated to his ship, and the Damsel shot out of the Tower's hangar bay.

But back in the Vanguard room, the leaders were having doubts. And Eris came into the room.

"He has no idea what he is facing. You must tell him what he is getting into." She said grimly.

"Would he have agreed if he did?" asked Cayde.

"Of course. He only took on two hive gods on his own and survived. Why do you insist on keeping the purpose of his mission from him?"

"If he screws up, Eris, you know what happens!" Cayde yelled back.

"Calm down, Cayde. We all do."

"Hello, little human readers! It's me, Discord. You know, the Lord of Chaos. You must be wondering: Why did I drag you from a strange plot development? Well, the writer was taking too long, and those Vanguard seemed so BORING and SLOW. Except for that Cayde fellow. He's good."

*What are you doing in my book?*

"Eh. Thought I'd improve it a bit. You know, jumpstart the plot a little. Introduce a few characters a little early. Cause a little Discord in places."

*Did I just hear a rim shot?*

"Heh. I'll still let you write. Besides, it's a good story. But there will be some phases where you have no control at all. Just let me take control of a few things. Like stealing away a bunch of characters from a few other franchises to fight the Hive. You shouldn't have made them do that, because now I got to do this to you."

*Well, I did want a Destiny crossover with something, but this is… unexpected to say the least.*

"Also, didn't you really want to say 'beam me up' with teleporters involved?"

*Shut up.*
