Thieves and outcasts have built a secret district on the rooftops of Fallen London out of planks and scrap iron. The view is good. The food is not. They like to talk about a 'bad altitude'. So basically it is an area "above" London, it is a massed construction of gangways, ropeswings, croocked brigdes and deadly drops, it is constantly being built and falling apart, its a good place to hide from the constables since they very rarely go there, though it is swarming with urchin gangs and raggety men, and is "ruled" by The Topsy King, the notorious beggar-king of the Flit. Although he's far from royalty, you should probably present yourself if you plan on being visiting often. And oh yes, he's supposed to be incomprehensibly insane.
Sounds like a grand place where Manfred gets the opportunity to throw people off of roof tops and watch them go splat on the ground.
As long as he dosent throw the wrong kind of criminal Dont want to anger one of the 3 crime kings of London
I have little to no Lovecraftian knowledge and what I do know comes from second hand, wikipedia, anime, and Hellboy. Does this qualify me for initiation?
