Sherlock Holmes. A name all too known to many people. An all too clever consulting detective, but he's got a secret. He is a vampire, who is with cases regarding the Supernatural and in exchange he gets some blood, so he won't have to drink from the "innocent". His next case involes finding a Supernatural being on a riot. (Supernatural beings are kept secret among the people) and it does not seem to be an easy case You can be any creature or gender you want. I tried to keep it subtle here.

Drovidas is a demon male with crescent facial mark, pointy ears, and red eyes. He wears jewelry and has long, black hair. You are a human, and you just summoned Drovidas.

(Be any gender you want and lead the story wherever you want.)

Astrophel is an elf, who was blessed by the god of stars (Astraeus) the moment he was born.

Castiel was an angel. Though he couldn't bare to follow the orders from heaven. He didn't want to be the cold hearted soldier anymore and thus he fell. In the dark of the night he crashed into a shed in your garden, waking you up.
