The Blood Mage

Summary:

Only a mage driven to insanity or desperation burned their own tissues for seidr.
Loki had far too much experience with both and even he wasn't fool enough.
But the Norns had never had mercy for the likes of Loki...

Stripped of the body he'd always known, Loki is bound in his true form, that of a frost giant runt barely on the cusp of adolescence. Yet no one knows what lies under the false image of the disgraced second Prince of Asgard, certainly not Thor. Odin knows full well that Loki would not survive the truth of his lineage being uncovered, and he still had use of his stolen relic.
However – weak from months in Asgard's dungeon after barely recovering from Svartalfheim and Thanos' ministrations – Loki is stolen from Asgard's dungeons by Thor. As the only known wielder of two Infinity Stones, the Avengers hope to use Loki to uncover the reason behind their appearance on Earth. Especially in light of the Mind Stone taken form as their newest ally: the Vision.
But they are not the only ones who have use of a bound child mage.
Fate has other priorities.

Notes:

My take on the concept of redemption by turning Loki into a child, with all the complications that may bring. If you are looking for Kid Loki (TV), that character is loosely based on the concept of Serrure in the Loki: Agent of Asgard comic series. You may enjoy this as well, but anything from the TVA story arc will not be touched upon in this fic.
Trigger warning: torture, child abuse, violence against a child.

This is not AI, and the fact that I have to say that is depressing.

Chapter 1: Prologue

Chapter Text

Didn’t do it for him.

Didn't...

Never for him.

His seidr was cloying. Sticky. Trying desperately to pull the flesh together where the crude blade had parted it. But he just had to hold it together a little while longer. Grungnir was heavy, thrumming with seidr against his skin. Familiar magic. The same seidr that had cradled his own as he was just starting to discover how to use it. Its presence made his gorge rise in his throat.

Didn't belong there.

How dare he…

 

Thor was standing in front of him, blind to the glamour lying thick over Loki’s skin. Blue eyes sad. Because Loki was dead...

He barely listened as he offered praise through Odin’s lips. Just knew it was all the things he had always wished to hear. That Thor was accustomed to, but still made him glow to hear. Thor’s face was pensive though. His brow prematurely lined with grief. He tried his best not to look. Otherwise he was certain he’d fall to pieces.

Loki’s silver tongue wove words through the headache pounding at his skull. He barely resisted clenching his teeth against the unpredictable pain waning and crashing over him. His seidr was angry at him. Demanding that his body rest. Demanding he make the hole in his chest a priority.

Thor offered him the damned hammer as a soft hiss of pain escaped him.

“It belongs to you.” the words tasted like ash in his mouth, even as he knew he spoke the truth. “If you are worthy of it.”

“I shall try to be.” Thor said solemnly, graciously. Yet some of the tension eased around his brother’s eyes. Relief, but not enough. Not the kind of reprieve justice would bring. 

Maybe he might even one day understand the use of it. 

Perhaps his adventuring will do him well. Thor was always at his happiest when he was off with righteousness at his back and something ugly to hit with Mjolnir. Loki hoped Thor’s newly found set of morals the Midgardians had so graciously gifted him will also keep him from getting himself killed.

He knew he should shut up. Let the glamour slip. Go lie down. But he still found himself giving Thor parting words that he knew the Thunderer needed. Words of pride to cut some of the strings of grief weighing down his brother’s heart. Even if it also had the added benefit of keeping the lout away from Asgard for longer.

“Thank you, father.” Thor said and strode off into the fading light with that ridiculous cape billowing after him.

“No,” Loki’s chest burned, but he still felt his shredded heart skip a beat. Finally, free. “Thank you.”

After all, the cur still left his body to be scavenged on that crumbling ruin of Svartalfheim.
