ASGARD: BIFROST
"Heimdall, you called me here, please stop talking in riddles," Thor implored the tall, dark gatekeeper who just looked down from his pedestal, looking as stoic as ever in his own golden armor.
"Midgard is under attack," he said simply. Finally, a straight answer!
"Who by?"
"They are cloaked to me," Heimdall answered. That was really useful. Thor knew of only one that could conceal himself from Heimdall; Loki, and his powers had been taken. "it is not your brother," Heimdall sensed his thoughts, "I see him, and he ventures forth, searching for help."
"Loki is coming here?" Thor was confused. If he was coming here, he would be using one of his secret portals, but how? He still had no power.
And then there was a blinding flash of light in the sky, and Heimdall grinned in a way he had never done before, "your brother returns."
Over the gleaming city the small Cessna rocketed, the first ever human craft to have ventured into this realm. There were few flat surfaces on Asgard, and most of which were on palace grounds, and not long enough for a runway landing. The only long, flat stretch that would suffice was Bifrost itself.
Thor was on the surface of Bifrost as the large, metal beast came in for the landing, touching down on Bifrost, and a metal man landed down beside him, and he was staring into the eyes of Tony Stark's one remaining super suit.
"Point Break."
"Metal Man." He admonished coldly. The plane came to a stop with an exceedingly good short runway landing procedure and a figure leaped from the cockpit. It was an incredible sight, the wings jutting out several meters beyond the bridge. Another figure leaped out in a long trench coat.
"Impressive landing, Hartman," Tony called to her as she approached. A smaller figure skulked behind her.
Loki smiled at Thor, "good to see you, I think."
