The battle between Vale and Loki alerted Asgard in its entirety. However, even then, it wasn't possible for anyone to reach Vale for help because of their rapidly changing position. The plan enacted to keep Thor safe from outside influence had now become a problem.
Still, the entire armada of Asgardian soldiers rushed over to the Sanatorium and was working together to find the chamber where Thor was being kept. In the meantime, Vale was kicking Loki's ass over and over again.
This wasn't surprising at all. After all, ever since being resurrected Loki had just been focused on manipulating others to achieve his means. After all, it was his speciality to get dirty work done without getting his hands dirty.
Thanks to his new habits of plotting and planning, he rarely ever practised warfare. As a direct result of that, he had gotten weak. Vale, on the other hand, had done quite the opposite. He was still cunning as ever, but ever since Asgard was restored he had made it his life's mission to grow stronger. Strong enough to protect Asgard from any danger.
Finally, millennia of excruciating training and pain was paying off. He was strong enough to take his revenge on Loki for what he did to Asgard.
Loki's body was covered in bruises and scars, while there was not even a single scratch on Vale. That was just as strong as Vale had become. As things stood now, he could even go toe to toe with Thor, until the latter got serious about killing the former.
Also, the state Thor was in at the moment, it was better to keep him asleep. Otherwise, he could even trigger Ragnarok by himself. Thor's rage was legendary. Some even dared to compare it to Shiva's.
Vale did not know whether it was true or not, nor was he interested in confirming that fact. His only concern was to either kill Loki or stall him long enough for the All-father to show up.
"I see you are not yelping anymore, Loki," Vale said before shooting yet another blade of god slaying winds, "I thought you said you were going to destroy me?"
Loki barely managed to dodge the wind blade before collapsing on his knees. Loki had not expected the weakest of Odin's sons to have grown this strong in his absence. Still, like always, he had contingency plans prepared for such circumstances.
The only problem was that he did not want to sacrifice his son to make his escape. But there was no other way. He had to call forth his most agile offspring, that was the only chance Loki had against Vale's godly winds.
Loki let out a horrifying howl that came out from the depth of his soulless bowels. The noise was so loud that even Vale, who had accompanied countless storms, had to force his ears shut as blood came gushing out of them.
It took a few moments for Vale to realise what Loki was doing. Vale tried to shut Loki down, but it was already too late. The one whom Loki wanted to hear his call had already heard him.
'I hope I will not need to abandon you this time,' Loki thought to himself as the creature lying in his own domain of misery and Chaos underneath Asgard rushed to the surface, 'Come forth, Fenrir!'
Suddenly cracks appeared in the golden floor of the Sanatorium. Vale had the most terrifying look on his face as the floors collapsed and out of the crack walked out the beast no one would have ever wanted to see.
In front was Vale was standing a giant wolf, covered in black fur from the head to the toe. The menacing look in his crimson eyes was enough to even make any of Odin's sons take a step back, except Thor, who was one of the gods who fought the wolf during capturing it.
Even as a newborn, Fenrir was stronger than quite a few gods. Which made the others scared of him as well. His absurd strength coupled with his seemingly limitless growth in size made Odin order to put the beast into sleep only to be wakened up to be fed.
However, their plans of taming the beast fell apart as he got stronger and stronger. Soon enough, no gods other than Tyr even dared to approach the sleeping beast. The redheaded god of Law, justice and formerly of war as well, became the sole caretaker of the wolf...
Until the day, Loki, Fenrir's father, rebelled against the gods in the greed of obtaining the throne. Loki snuck into the chambers where Fenrir was put under sleep and used the magic of the giants to wake him up.
However, before Loki could have completed the spell, Tyr caught wind of the situation and stopped Loki midway. However, Fenrir was already awake and he was mad. Since the spell was still incomplete, neither Loki nor Tyr had control over the beast.
Tyr, being the brave and the only affectionate god among Asgardians, immediately rushed to calm the wolf down. He slowly inched his hands closer and closer to Fenrir's head to try and pet him like Tyr always did. However, it was a mistake... a grave one.
In his confused state of mind, Fenrir bit Tyr's head off, killing the one benefactor amongst the gods the wolf ever had. By the time Fenrir awoke completely, it was already too late. Tyr was dead and the taste of blood in his mouth racked the king of wolves with guilt.
As for Loki, he being the mastermind he was, manipulated his own son into thinking that the gods fed the wolf something which made him hallucinate and kill Tyr. He branded himself as the hero who got the wind of the plan and wanted to help Tyr but by the time he got there, it was too late.
In his susceptible state, Fenrir believed his father and swear to destroy Asgard along with the gods. Which he did as Loki overthrew Odin and captured the throne for himself.
After a few years, Loki was killed and as soon as the other gods revived again, they ordered Fenrir to once again be forced to sleep. Some would have called it a foolish move, however, inspired too much fear in them for them to let him out from under their watchful eyes.
Thus, they unanimously decided to force the wolf to stay in their stronghold of Asgard. But this time, they had chained him using chains made of Celestial Silver. Still, none of them was aware that even in his death, Loki had messed their plans up.
It was estimated that it would take seven chains to safely bind Fenrir. However, out of the seven chains only six were made of celestial silver while the remaining one was the fake one. No one except Loki knew about it, and no one except him could make the call that would agitate the wolf enough to break free of his chains.
"Hello, father..."
Fenrir let out a growl to greet his father with a bloodthirsty look in his eyes. Loki knew what that stare meant because the last time they had met each other, Loki had made Fenrir a scapegoat to distract Shiva long enough for him to escape.
However, the plan failed when Fenrir realised what was going on and refused to battle Shiva, allowing the Immortal one to kill Loki.
In the meantime, Vale had a terrified look on his face. It wasn't because he was afraid of Fenrir, but because of the prophecy related to Fenrir... 'The day Loki's second son would break out of the chains binding him to Asgard, would be the day Ragnarok begins...'
"What have you done...." Vale managed to mumble a response.
