As I was searching through mythological creatures, I read about Kresniks, which are creatures from Croatian mythology. Sometimes called Cruxim, or Dark Angels, they dine on vampires. I decided to explore making my hero that: an angelic being whose mission was to kill vampires, because how can you be considered holy and yet spend your life killing others?
And then I wondered, what if someone dear to him became a vampire? How would he handle that when his mission is to kill them all?
In mythology, Cruxim often have black or blood-tipped wings and they might be able to "warg' into wolves. The great thing on focusing on this little-known mythological creature was that I could really make Amedeo's backstory my own, and create these fantastical "Creches" were the Cruxim live.
