I've been looking at this story for a long time. I even tried to search the internet - but I still can't find anything about these characters.
Although the pictures look interesting.

Hey Marksan! Rowee and Darien are OCs of mine and I use them in an art roleplaying group. The species is Rukaan but the group itself is called Fields of Valhalla. You should be able to find more info with that name or by clicking the DeviantArt link. ^^ If you're looking for a written piece about them, I have yet to explore that avenue but I'm glad you like the work!

Thanks for the explanation, I appreciate it.
I read a little about this world - and now I know at least approximately what it is about. And although I have not yet understood everything, I must say that this is an unusual - and very interesting world.
