Tony lifted the large, heavy metal cube onto the white toped lab table. His arc reactor's blue light beamed through his navy blue AC-DC, long white sleeved shirt. The sleeves themselves have been rolled up just passed his elbows.

"What the hell have you got your hands on now?" Tony looked up to find Steve leaning against the the labs doorway.

"Not sure." He replied, rubbing his freshly trimmed goatee.

"The great Tony Stark doesn't know!" Steve pretended to be shocked as he approached. "If you don't know we're all doomed." Steve said sarcastically as undid his brown leather jacket, revealing his grey t-shirt underneath.

"What do you want Rogers?" Tony asked, his eyes fixated on the metal box.

"I heard Thor found you a new toy."

"A toy I don't get to keep." Tony sighed, turning behind him he collected his tablet, his fingers rapidly tapped the screen. "Thor is handing it over to a friend of his, Dr Strange I think his name was."

"Surprised Banner isn't helping you." Steve told him, his eyes searching the room for Tony's fellow scientist.

"He'll be here soon; said he was meeting Natasha." Tony's eyes still didn't move from the small screen he held in his hands.

"How long you got with that thing anyway?" Steve asked leaning in for a closer look. There were distinctive markings that could be mistaken for text, as well as three large circles on each face that intercepted each other. The metal itself was a deep dirty orange, covered in scrapes and scratches, it looked ancient.

"Only a few hours." Tony reluctantly replied. Steve wasn't picking up the fact that he was disturbing Tony, wasting some of the precious time he had to work on the strange piece of technology. "Friday what you seeing?" Tony asked his artificial intelligence, finally looking up from his tablet as blue lights from above scanned the basket ball sized cube.

"The cube is still emitting the same frequency that you picked up on before." The slightly robotic female voice spoke, her voice coming from speakers dotted around the large lab.

"Is it transmitting or receiving?" Tony asked the A.I, a screen appeared on the table in front of him. The screen showed the signal in question, the waves fluctuated rapidly.

"Both." Friday replied, the signal in front of Tony suddenly split showing two distinct wave patterns. Tony leaned on the white table, trying to wrap his head around the mystery of what he had in front of him. Steve was watching closely, trying to follow along.

"Where's the transmitting signal coming from?" Tony asked, tapping at a few buttons that had appeared on the table screen.

"The centre point of the cube." Friday told him.

"Start triangulating where the signal is transmitting, and see if you can locate the point of origin for the signal it is receiving." Again Tony tapped at the screen on the table, looking up at the box every now and then, seeing if there was anything he had missed. "I have a sneaking suspicion their going to be from the same source."

"Where did Thor even find it?" Steve pretended he didn't see Tony role his eyes, thinking he was merely annoyed with his lack of knowledge.

"Another realm under his father's rule, buried in a secret vault that hadn't been opened in millions of years." Tony reeled of the information with ease, even with ninety-nine percent of his attention on the information being displayed in front of him.

"Stark." Even when his name called Tony didn't look up. "Get Thor to get that thing out of here." Natasha was clearly agitated, Bruce quickly followed after her as she charged into the white walled lab. Her long red hair made her angry blue eyes more vibrant, seeming to burst with colour.

"It's out of here in a few hours, don't worry." Tony still didn't look up as Natasha approached, Bruce at her side. Only just having returned from a mission she wore her usual black body suit, a number of gadgets strapped to her belt, one gun fastened to each thigh. Bruce adjusted his glasses, watching as her hand twitched near one of her guns, he could see her pulling it on Tony.

"Not soon enough." Natasha's right hand now rested on one of her guns.

"Tony." Bruce finally grabbed his attention, Tony looked up, confusion was clear of Steve's face, he was lost within the technical terms. Natasha's eyes burned with rage, while worry was plastered all over Bruce, from his face to body posture.

"Steve, I have your shield." Tony suddenly changed the subject, he turned his back to the others, making his way deeper into the lab, before disappearing from sight. He soon returned, freshly painted shield in hand. "Try not to chip the new paint job." Tony told Steve as he handed over the shield along with a new harness for it. "Try it on, makes sure it fits." Tony told him as he returned his attention to the cube.

"Stark if you don't get that box in Thor's hands and off this world in the next few minutes I'll take it from you myself." Bruce watched Natasha unclip her gun from her thigh, she held it firmly in her gloved hand.

"Son of Stark, there has been a change of plans." Thor's voice boomed as he turned the corner into the lab, his hammer in hand. Tony threw his hands into the air, his quite afternoon of studying an interesting new piece of ancient technology ruined.

"You said I had a few hours." Tony argued, now five people including himself standing around the table.

"Dr Strange has urged me to deliver the box to him immediately." Thor stood out in the white room, his bright red cape dragged behind him, his silver metal and black chest plate as shiny as Steve's shield, that he had now attached to his back via the new harness.

"At least give Friday enough time to track the signal." Tony asked, now his time frame considerably shortened he was working away, with another screen now beside the first on the table, he was examining two sets of data simultaneously.

"I am sorry Stark; I must take the box from you." Thor went to grab the box, his hand only just touched the surface and he recoiled in pain. The others jumped back in surprise. "What trickery is this?" Thor demanded, thinking Tony had done something to the box.

"Friday what's going on?"

"The core temperature of the cube is rising considerably, also the signals being transmitted and received are no longer measurable" The box suddenly began to vibrate, slowly becoming more violent with each second. Everyone took another step back.

"Tony?" Steve questioned, also wondering if this was his doing.

"Wasn't me." He replied, kind of annoyed all the blame was on him. Deep blue lights suddenly spewed from cracks in the box, the table now shook, the box becoming more out of control. Tony stepped back and again disappeared into the lab, Bruce rushed over to the screens Tony had been working from moments ago, his eyes twitched form left to right as he read the data.

"It's as if its powering up." Bruce deduced from the information in front of him.

"Bruce move." Tony's voice spoke through the Iron Man amour, his voice tainted with a mechanical tone. Like Thor's cape, the red and gold of the Iron Man amour stood out like a sore thumb in the plain white room.

"Tony what are you doing?" Natasha questioned, her finger now around the trigger of her gun.

"It doesn't want to be touched, so let's touch it." Tony without hesitation reached out, the familiar mechanical wheeze of the amour sounded as Tony moved.

"Tony don't!" Steve protested. But before Tony could lay a finger on the box, the blue light exploded from it engulfing them all.
