The Search for Loki by UnderwaterArch

Summary
Loki was gone—at least, the part of him that Sylvie knew.
Upon travelling to New Asgard to find his brother, Sylvie buries a lock of his hair as a way to say goodbye. But soon after, she finds a small tree has grown in its place. With the help of her new friends, she investigates the mystery of the tree—and its connection to Loki.
The feel of cool damp grass on her hand. The smell of ozone on the breeze. The dew seeping into her pant legs. Everything felt in focus and so very real, not at all like a dream.
And Loki was still there.
He’d spoken, he’d looked at her, and then he’d laid his head back down and closed his eyes. Completely still, except the rise and fall of his steady breathing.
Alive.
It would be easy for her to remain transfixed on this subtle motion, the endless pattern of inhale/exhale. She shook off the temptation and looked him over; he was covered in a thick shiny substance. Transparent for the most part. Tentatively, she tried to wake him.

Summary
As an infant, Loki is promised in marriage to Odin's son Thor in order to end the war between Jotunheim and Asgard. Not having been permitted to meet before the time of marriage, neither of them is looking forward to it. Especially, since they've both fallen in love with (the same) someone else.

Summary
Loki helps the new TVA build a society for all the variants with no place to go, like him.
Sylvie and his other self found each other and are living the life he desperately wanted. Unwilling to risk making a version of Sylvie that won’t be ok, he tries to move on with his life, but a Loki variant who looks exactly like her is making things complicated.Loki tries his best to separate the two of them in his mind while helping the variant heal from eons of TVA experimentation, and his own heart in the process.
He didn’t flinch away from the touch, but didn’t respond to it either, “Did you just come here to flirt, or is there something else you wanted?”
His counterpart sighed in resignation, “No, I do have something to tell you,” he dropped his eyes to the floor, then looked up and grinned widely, “but you’ll have to catch me first.”
With that, he disappeared in a flash, hoping to tempt Loki into a magical game of cat and mouse.

Thor fell onto the beach one day by UnderwaterArch

Summary
Thor falls into another universe and is forced to kill another version of himself. Then he hears a song from the water, that he simply cannot resist.
It was then (as he made a mental note never to use a narwhal horn as a decorative item) that he heard the song.
A hauntingly beautiful song; so sweet he felt he could open his mouth and have the melody melt on his tongue like spun sugar.
Surely it could only have come from the most talented singer in Valhalla, it so enchanted him.
It drew him towards the water, to the end of a long wooden dock. There, he found the source of the music and stopped short.
The singer rested his elbows on the end of the dock. The rest of his body dangling into the water and he had obviously just been swimming as his long black hair was dripping wet.
When the man saw him, he stopped singing, “You killed my brother,” he said.
“I-uh,” Thor stammered, “I’m sorry. It was an accident. I fell on this hut you see, and he attacked me-“
The man halted Thor’s apology with a wave of his hand. “No need to explain,” he said, “You’ve done me a great service. My name is Loki and I greet you warmly.”

Summary
Loki is the black sheep of the prestigious Odinson dynasty. His life has been a whirlwind of indulgence without consequence - but now his adoptive father has firmly thrown down the gauntlet and threatened to cut off Loki's inheritance if he doesn't clean up his act.
Begrudgingly, he allows himself to be checked into a private rehab facility. He just needs to make it through the 12 week program sober, and then normal service can resume.
However, one of his peers, Sylvie, takes an instant disliking to him and seems set on reading him for filth at every opportunity.
