I often, when I'm building languages, there are a lot of different ways that I go. I am not a philologist like Tolkien was. I'm not a linguist. Peter is, my editorial assistant, but I am not. I have had a little bit of schooling in linguistics, but not enough to be creating complete con-langs out of nowhere. So I'm usually using a few tricks to develop my language, one of which is to look for historical languages and seek inspiration from them.
And the pitch for myself on the whole thing, in Fjorden, was what if the Vikings had created a very hierarchical religion like Catholicism, and had instead of conquering the world as Viking, Nordic destroyers, they had become a religious group. They're really based off of the Geats, which is Beowulf's people, which are Nor--are British, they're British Vikings, basically. And so when I was developing them, I was using a bit of Nordic--old Nordic and things like that--and I'm using a bit of old English, and just trying to get that feel. In Beowulf, because in Beowulf they have some Danes and you have some people from the British isles, and there's this crossing over, and things like this, and it's this interesting sort of mix and hodge-podge of cultures and languages, from, 1000AD, and i really liked that feel, I really liked that linguistic flavor, so to speak, and so, I was really reaching towards lots of names out of Beowulf as inspiration.
