Once upon a time there was a half-demon named Doyle. Doyle was trapped in his boyfriend's flat while the world went to shite around him, with nothin' but copious amounts o' alcohol and a kitten for company (Flemming says hi). Useless Doyle felt useless. So useless Doyle decided to make a very self-explanatory diagram.
See? Simple solution. So please to be castin' spells now, witchy types.
