A lot of folks have asked what the influences on the Shard in Sister Claire were. Shards are born from the energia, pain and raging emotions of people who have died traumatically (usually en masse) so I wanted the creature to look like a a physical manifestation of that.
Many correctly identified the influence of the creatures from Princess Mononoke. I also wanted it to have a hint of dragon-ness (using my favorite dragon for inspiration) and Ash suggested looking at the eyes in Watership Down to give the creature a truly terrifying, manic look.
This is not the Shard's only form, though. I'm excited to show how it will evolve! 8D
