Finding warmth

She had to find shelter. Kate didn’t know where this was - it felt familiar and off, all at once - but she could tell it was getting late, and whilst the mistful rain had stopped, she knew enough to know the night would be cold enough without it.
Even if she had more to wear than a frown.
After ever more walking, a tree came into view, sitting on the edge of a clearing. It was ancient, with thick boughs, thicker green. The grass nearby looked soft enough, and there was a patch of dirt, shaded.
“Finally,” Kate murmured, and surprised herself with how her voice caught on itself, after so much quiet.
Kate was a rambler and proud, and such lengthy silence was a stranger to her words. She tried out a few more. “No idea where this is. We know that. Already referring to myself like a collective, that’s a good sign. But we’ll get out of this.”
She gathered the driest twigs she could, protected from the rain by their still living brethren, and after searching, found a flint that looked - and Kate tried not to think of the irony - exactly like an arrowhead, sharp edged and gleaming.
She’d learned this as a party trick, never knowing how useful it would be, and struck the flint against another, vaguely triangular stone, a few times, until the sparks caught a leaf and a small fire crackled into **** life.
It was heat, and more than that - warmth.
“Tomorrow, we’ll figure it out, yeah? Yeah.” She told herself.
She couldn’t quite sleep, the bark of the trunk digging into her bare back distractingly, her thighs and buttocks and calves scratchy against dirt and grass, but slipped into a trance like rest, staring at the flickering orange.
Perhaps she even would have slept, had it not been for the gleaming blue sword that quite suddenly pressed itself against her throat, and the women that seemed to slink from nowhere.
The sword owner, distantly familiar, clad in white and gold armour, looked down at Kate with something annoyingly resembling a smirk.
“A fire has been lit under the Ash. Our quarry sits here, bare and ****.” Her voice became a yell, and Kate was frozen, as she tried to catch up to what was happening, resisting the urge to cover, reminded harshly of her total nudity. “Valkyrie of the Realms! Shall we begin our hunt?”
