It's not often that I find myself really enjoying a fanfic for the story itself, not just the characters, but I am really loving this. It's so vivid in its imagery and the tone is... I don't know, soothing? It's hard to describe. It makes me think of the CDs of soft music and nature sounds my mother plays to relax. Beautiful. Completely, utterly beautiful.
I love the back story, the details of the culture and customs. I was very big on various mythologies a while back, including Norse, and I find myself nodding at points thinking "Oh yes, of course."

One question: I was intrigued by the foster-fathers, many cultures have practices of fostering out children to other homes like the squiring in Old England, and I was trying to figure out if that's what this was. However comparing the two chapters, I'm now a little confused.
Chap1:"Viggo, his foster father"
Chap2:"He’d visited... his foster father in Reykir", which seems to be a different person if he's coming back to Viggo. Isn't Viggo rather his step-father? (married to Elijah's mother.)

I am definitely bookmarking this and I look forward to more!
