Felim collapsed into the snow, exhausted. It felt like it would be the last fall this time, his limbs stiffening and flesh numb. The adventurer had heard of natives that thrived out here, men who slew bears and made coats of seal fur. But who could build anything out here...?
Just as he felt light start to fade, Felim cast his gaze up to see the sky one last time. He was startled - or would have been, if his body had the energy - to see a furred hood and a leathery face with a toothless grin. "Ho there, brother!" it spoke. "You came to just the right place."
A culture must hide its hands in the arm of their clothing as a sign of respect and peace. When approaching somebody you show them respect by crossing your arms and hiding the hands in the shirt sleeves. Nobody worries about hidden knives and such, it is the threat of magic that this custom was created to prevent.
