Dante’s Inferno (Map) by somnium-maris on DeviantArt ... I like the style, but the descriptions aren't entirely accurate (by the artist's own admission) due to basing it only on a portion of the video game adaptation.
Said to be a canibalistic disease of the heart/mind in which the affected person consumes the lives of other humans and things with no regard for the natural balance of things… equated to greed and a deep fear of lack.
Hierarchy of Angels and Demons by ~justdejan on deviantART.....until the second coming of Christ the battle will rage on. Pinning this for later, I don't think I have been introduced to all of them yet, only just finished s5.
