Moses Walker
From Tardis Wiki, the free Doctor Who reference
Moses Walker was a chimney sweep who lived in Victorian London. He was the head of the Guild of Smoke and Shadow.
Missy tracked Moses down by torturing his location out of the Phoenix — a fire elemental who was a phoenix. Missy threatened Moses for the location of the Arcane Gatekeeper and, when he failed to give up the information, pushed him off the rooftop they were standing on. Before he hit the ground, Moses was teleported to safety by Mr Cosmo. (AUDIO: A Spoonful of Mayhem [+]Loading...["A Spoonful of Mayhem (audio story)"])
