Asgard, Universe 20618. Ragnarok
The Bifrost had failed three decades prior. It was a living, breathing force of the universe, true, but not truly sentient. Because of this it could be tamed and used, but not coerced and reasoned with.
Loki knew this, but it didn't make what he had to do any less frustrating. If they could simply ask the bifrost to do what they needed things would be much easier. As it was, he had been trapped in the Bifrost chamber with his immediate family and Heimdall for a week as they made the necessary preparations to ensure the survival of their family, and more importantly, their people.
"Brother!" Shouted the ever boisterous voice of his once much hated brother. Things like sibling rivalries began to feel much less important when the death of everything you knew was creeping upon you. "Tell me you are almost done! The battle will be upon us in a matter of hours, strong we may be but the shard must be completed before the battle."
Loki grit his teeth as the sweat beneath his helmet built up, outfitted for the upcoming fight as he was.
"I have told you once and I will tell you again brother. The Bifrost will start the transfer between realities exactly when it is ready, not before or after. We are not simply transporting down to visit one of the nine realms, we are orchestrating a complete reality shift months in the planning. As it is we'll have to hold him off for weeks at the absolute best!" He snarled from his position, held upside hanging above the bifrost lines by Thor as he had for the last 20 hours, positioned perfectly where the Bifrost had begun to intersect from one reality to the next of the realm of Midgard. They were not sure why, nor would they question it given the circumstances, but the walls between realities were the most thin for the Realm that was home to the weakest of their subjects.
It was as Thor opened his mouth to continue the pointless bickering that their father Odin stepped forward from beside his worrying wife and quietened them with simply his presence as he turned to the Guardian of the Bifrost.
"Be quiet, the both of you. Heimdall I believe it has started?" He turned to their silent and stoic guardian who had stood without moving for as long as they had been in this room, his chiselled dark features turning to meet his King's eyes before simply nodding.
In the next second his blade, the key, plunged into the socket for the Bifrost and activated it at the exact second the Bifrost lurched as an ocean might do, the tear they had fostered over the last month splitting open just enough for the shard to slip from Loki's fingers and into the Realm beyond.
Thor quickly pulled his brother up just as the Bifrost would have struck him. While he would likely have lived given their fortitude as Odinson and giant alike, Loki did appreciate not having to put up with the burns he would have suffered. There were few weapons as destructive as an active Bifrost.
"I suppose I should thank you," he sniped as he walked towards the entrance to meet his parents who had already set to leave before the job had even completed. He wouldn't admit it, but knowing how absolute the faith in him for the task was heady. Even after having proven himself a few years prior he knew his parents often considered his brother to be quite unreliable.
"No brother," said Thor, catching him by surprise at his unusual sombre voice filled with conviction. "It is I who should thank you. A great warrior I may be, but this isn't a battle I could ever win. It is your plan that will see us to victory on this morrow," he spoke as he picked up his hammer Mjolnir and moved to follow.
"Well," Loki nodded as if to agree before stopping and squaring his chin as he pulled the blades from his back as his family plus Heimdall fell in to step as they crossed the Bifrost bridge. In front of them the sky had already begun to turn to red, a sign of the times about to start. "If we're being honest, I suppose we'll be thanking either our brother or sister once all things are said and done."
"The Ravens tell me it will likely be a daughter," their mother spoke for the first time that day, in silent vigil as she had been. "With the intelligence and wit of my youngest, the strength and courage of my oldest," she met their eyes as she spoke. "But above all, with the tenacity and conviction our family has always held."
She turned to look back at the Bifrost which pulsed beneath their planet one last time as the exchange was completed and the tear between worlds healed, for now.
"And she will need all those things if my visions are to be believed. Good luck to you, my daughter," and with that she turned to fall back into step.
Their saviour would have their own battles before they could meet for the first time, but they too had their own war to fight.
A/N - I actually had little trouble with this one. I actually have a decent outline for where it would go. It'd start out pretty Earth Bet heavy with very little to do with Thor/Marvel until a decent way into the story. I did, however, have a lot of trouble with ending the prologue, which is what this chapter would be. I don't like the last sentence, but I didn't want to remove it either, but I also couldn't bring myself to add anything else because anything else would have been needless fluff and distracting from the setup to the actual story.
After this I have an idea for a Worm/Eureka Seven cross that was actually the first thing I tried to write but I was incredibly unhappy with but I'm going to try to crack out sometime soon-ish. After that, I think I'm going to give writing out a second chapter for one of these a go. I'm enjoying practising writing and maybe with enough I might try to crank out an actual full story. Anyway thanks for reading, pop a suggestion in the reviews if there's a crossover or idea you wanna see. Can't promise anything but I'm always happy to be inspired to write.
