Sinistora is the black demon dog of Kharl the Alchemist. He doesn’t have as profound a task as the Left and Right Birds. No, his goal is far more simple and basic. His goal is to protect Kharl’s home and secrets.
He created the dog, as he did the birds. It is said that Sinistora is an elemental demon, being one of the only creatures to master all the elements and still so loyally serve.
