DISCLAIMER: I am well aware of the timeline inaccuracy of this artwork. This is set in 1814, while the famous Icelandic lullaby (of which I used the lyrics) was written in 1911. Please do not comment about this inaccuracy, because I've already known it.
I'm so sorry, I drew angst.
At least it's historical.
Anyway, I feel somewhat guilty for being too obsessed with DenNor these days - I didn't even like it, originally (now I do, don't worry). I decided to go with some brotherly and emotional NorIce, to make up for my laziness over my doujinshi back in July 2013.
Now, lullabies have always fascinated me. Especially mysterious and creepy ones. I recommend you to listen to this song, Sofðu unga ástin mín (Sleep my young love), Sung by Sissel Kyrkjebø. You can read more about the lullaby here.
I've modified a lyrics a tiny bit to fit.
Headcanon: Norway used to sings lullabies in both Norwegian and Icelandic, and whenever young Iceland is particularly upset, Norway would sing only in Icelandic. Because he knew Iceland liked that (though he'd never admit, even til now). Nowadays Norway sometimes sings in Icelandic mostly to tease his little brother - Iceland is only half annoyed, actually.

Sofðu unga ástin mín was written by Jóhann Sigurjónsson. The translation I used belong to Otakuso
The artwork belongs to me.
