Ouroboros Spine I am that is

It had been an evil sign that Goldhawk's shivers had stopped, but as the stranger began to deliver warmth to him, he somehow felt colder... but this, in turn, was a good thing. Because he began to shiver again. He had frostbite somewhere (better not be in the important places, he thought dully), and his temperature refused to regulate. At least he was only feeling one thing before: ice ice ice. Then this stranger came along and mixed things up. Urgh.

Death is as toasty as my auntie's temper, I'll h-have you know, he contradicted indignantly (albeit very weakly). But... hmph, how did he know Goldhawk was a warrior? With great difficulty, he finally opened his frosted eyes to the night. And there he saw... himself. He blinked.

Quite certain I'm already dead then, wot wot, he realised at this bizarre revelation. Back to bed for old Sergeant Goldhawk. He closed his eyes again.
