The King of all things troll-ish who reigns over a land in which the people are constantly crying and everything hurts. Reichenbach's soundtrack is played on a loop in all the supermarkets, and Doomsday is played in all the local bars. In these bars you are personally waited upon by a Mark Gatiss, who will serve you your soul on a silver platter.
The writer and co-creator of BBC's Sherlock. He also writes for Doctor Who. Often referred to as Satan, Moffat is an evil genius, along with his equally praised and equally evil cohort Mark Gatiss (aka Godtiss). Contrary to popular belief, Mark Gatiss did not write the Sherlock Season 2 finale, the Reichenbach Fall. Steve Thompson did. However, The Moff does have a building jump under his belt (I am referring to Amelia and Rory Williams' "The Angels Take Manhattan").
