But the troll, anticipating her move, roared, "ILL TA...KE Y...OU!" mimicking human speech with a grotesque parody.
It lunged, its maw impossibly wide, metres from where she lay. Fast. Reactable, but far quicker than anticipated. Her reflexes had failed her. The troll's jaws ripped open, revealing a distorted reflection of human teeth—monstrous steel shields, mortars and pestles glinting in the dim light. A horrifying sight, a caricature of humanity.
It'll take one of my arms… But I can heal that with runes!
Gritting her teeth, she steeled herself. Less than a second had passed since the troll marked her. A flash of high-speed battle. The monstrous eyes darted, its triumphant malice fueling a renewed surge of acceleration. Its maw stretched even wider, surpassing its natural limits. It craved more than just an arm. It wanted everything—flesh, bones, organs, and even brain. Aslaug, oblivious to the ancient Bergrisi giants' bloodlust and hunger coursing through the troll, finally grasped the gravity of the situation.
"...!"
A gasp, barely audible, escaped her lips just as...

"Hey, you."

A blur of intervention.
Faster than anything else, Ragnar Lodbrok, muscles coiling like springs, launched himself with explosive speed. In a flash, he latched onto the back of the troll's head. A crisp thunk echoed as metal pierced flesh through the troll's mushroom- and conifer-ridden hide.
The troll lurched, a half-breath delay in its attempt to dislodge him. But even that sliver of time, no, even half of that, was sufficient. A gaping opening emerged, enough to land a fatal blow.
His biceps bulged, veins popping as thick fingers clamped onto the troll's head like a vice.
"Odin!"

Oh all-knowing, all-powerful god! Bear witness!
The ancient power pales before him!
The green troll withers before him!
Behold the wrath of the Berserker! No earthly might can stand against him!

──── His grip pulverised its cervical vertebrae!
Pure, unadulterated force delivered the final blow. With tremendous strength, Ragnar snapped the descendant of giants' neck using only his bare hands.

The troll went limp, collapsing with a heavy thud. It desperately tried to regenerate itself, an act rendered futile by its crushed spine and severed legs. Burning outpaced healing. As plumes of black smoke multiplied to ten, the green flesh ignited, burning completely to ashes within seconds.
"You all right, Princess?"
"...Yep."
The brush with death hung heavy in the air, unspoken.
