Prologue

Heimdall was supposed to be watching Loki, supposed to be making sure that the All-Father's youngest son was behaving himself. And he would turn his all-seeing eye to Loki - in a minute.

Although Heimdall made it his policy to never get to involved in the lives of humans, he was currently enthralled by the battle that Prince Thor and the Avengers were fighting. In all his days, the gatekeeper had never seen warriors so fierce nor beasts so monstrous. Truly, these were no regular mortals.

As if he had heard Hiemdall's thought and wished to enforce the idea, the blonde man brandishing a shield rushed forward and struck the large, violent green monster in the chest. The hulking creature stumbled backward, shocked that it had almost been bested by Steven Rogers. Quickly recovering, it let out an ear-splitting roar, picked up one of the mortals' yellow public carriages, and hurled it towards the main group.

It collided mid-air with a green force-field, exploding in a bright ball of flames. Heimdall's curiosity peeked as the one who had projected it stepped forward. Carter Banner held her hands out in a gesture of peace, cautiously approaching the beast known as the Hulk.

"Bruce." The woman's voice was both calm and pleading. "I know you can hear me. Please. You're better than this."

Heimdall subconsciously cocked his head to the side as he watched the Hulk's expression change. Confusion and conflict of the most primal sort, followed by an elementary understanding. Then, those innocent emotions were wiped completely from it's face and were replaced by hatred. The creature's already glowing eyes burned brighter with abhor, and it let out a growl that made Heimdall's vision of the battle shake.

The roar that came from out of his window struck a fear in the gatekeeper's hear that he had never experience before. Turning his eye, Heimdall saw what must be the most ugly and ghastly creature in all the nine realms. Like the prehistoric brutes that had once roamed Midgard, scales and spikes covered it's entire body. However, it was disturbingly humanoid. A mixture of man and beast in the most extreme form. An abomination.

It lunged forward, targeting Carter Banner. Claws outstretched and yellowing teeth bared, it was set to send her straight to Hel.

Until the Hulk interfered.

It leaped in front of the force-field user, shielding her from the fatal blow. Enraged that he had been denied a life, the Abomination took out his outrage on his fellow monster, digging it's elbow spike's into the Hulk's green skin. With a cry of pain and rage, the Hulk wrapped meaty hands around his foe's neck, locking the two of them in battle.

"Shoot him, Clint!" Carter Banner shouted desperately, turning to her companions.

An archer with a drawn bow, the agent known as Hawkeye and the man known as Clint Barton, furrowed his brows, hesitating. "Which one?"

"Blonksy!" Natasha Romanoff snapped as she picked herself up from a pile of asphalt and other manners of debris.

"Which one it Blonsky?"

Heimdall heard the normally loud crown Prince of Asgard speak for the first time. "The one that is not Friend Banner!"

With an almost ashamed look, the archer huffed and drew his bow back tight. With precision that could best even the highest ranked archers of Asgard, Clint Barton let the oddly shaped arrow fly. It landed in the middle of the Abomination's forehead.

As if it had been dealt a terrible blow, the reptilian creature crumpled to the ground, twitching ever so slightly.

The Hulk let out a roar before running off into the city.

Now that the battle was over, Heimdall turned his gaze to the trickster, the god with the silver tongue, the only one in all the realms who could successfully shield himself from the gatekeeper's watch: Loki.

But this time, Heimdall could see the second prince.

And this time, Heimdall was not amused.

Loki was locked in some sort of prison, a metal ball that had power just coursing through it. The sorcerer was chained to handles that stuck up from the contraption, and for once in his life, he did not look as composed as he should. Panic, fear, and reluctance was all clearly written across his face. His eyes were locked intently on something, or someone, that Heimdall could not see from this position. So he changed his point of view.

Ah, yes, the young Roan Lokison. From what Heimdall had seen so far, this one would not be a problem. In deed, he was as kind as he father had been devious at that age. But something was amiss. Very amiss.

Roan's neck was entrapped by a thick arm covered in green cloth. As the gatekeeper's gaze traveled upwards, he saw a man who's eyes were as dark as his soul. Even from the other side of the Bifrost, Heimdall could sense an ancient evil radiating from him. Just one look at Victor von Doom, and it was clear that he was up to no good.

"Now, now, Mr. Laufeyson," the Latvertian king said warningly. "I'm a very busy man. I have things to do. Hurry, if you please." For effect, Doom tightened his grip on Roan's neck. "Your son and I are waiting."

Loki ground his teeth, then placed his hands on the handles he was chained to. Almost immediately, the circular bars around the device began spinning. Magic washed over the scene, momentarily distorting Heimdall's view. Transporting. Doom was forcing Loki to open a portal to another realm. But which one? And for what purpose?

The speed on the spinning increased dramatically, and sparks began to fly from the machine. Heimdall's window into Midgard began to blur, and soon the gatekeeper could only hear what was going on. A cry from a scared Roan, a grunt from Loki, and a cackle that sent chills up the Asgardian's spine from Doom.

And then everything was clear again. Heimdall could see the room that the three had occupied mere seconds before, but he could not see them. He searched and searched, but it seemed that they were beyond even his view now.

Without a second thought, Heimdall abandoned his post and set off in search of the King.
