This is something of a game but also an exercise in creating game content. The idea is to create a character, either one from a fairly well-known source outside of the 'Dresdenverse', or new one that doesn't appear in the books, but has a High Concept and description that fits. Include names, aspects, skills, powers, etc. - everything that would be needed for someone to play the character or for a GM to 'borrow' and use as an NPC. Use the refresh level necessary to represent the character, without going overboard (in other words, try not to jump straight in to 'Submerged' - Ha!). If you have an idea for a new Character Design Challenge, copy this introductory text and paste it into a new thread.
Let's start things off with someone that would have a Pure Mortal template:
Dexter Morgan, from the Showtime series that shares his first name.
Happy Hacking!
