I recently watched old episodes of Dr.Who again and the episode “The Beast Below” reminded me very much of the atmosphere of Fallen London or rather “Sunless Sky”. Except for a few small things, the whole episode would have fit wonderfully into the setting.
In the real Fallen London, the only thing missing is a somewhat bizarre character who constantly travels through mirrors into new adventures and a suitable name. Although time travel would also be an option, at least to some extent, in Sunless Sky.
In any case, I’m really looking forward to the TRPG and the opportunity to introduce new characters into the world on my own. There are a few that could be easily reworked to fit into the Setting of Fallen London.
