I've tried looking up this series after seeing your drawings of all the characters and all i could find was...your drawings.

I found it after dropping the h (apparently' it's Eterna), and if you haven't already watched the tv series adaptation of Game of Thrones that might be a good indicator of how an adaptation of something of that magnitude (as Reflections of Eterna looks pretty epic as well) would go :)
