To put it simply i want to write a short story in a H.P. Lovecraft type style based in the city of Seoul, South Korea. I am currently living in the city so writing about it is not an issue but I have no idea where to put the damn monsters.
I know how i want them to look. I know what kind of nasty things they do to people. I have them pretty much fleshed out.
And I don't have a damn place to put the buggers.
Seoul is the second largest city in the world next to Tokyo but as far as i know there is nothing like Undertown here. There are the subway tunnels but they are all pretty new and well maintained. The sewer system is also very modern. There are tunnels, mostly dug by people fleeing North Korea, but they are found quickly and either sealed or collapsed quickly.
The problem is putting underground system that normal people couldn't find easily but could still access quickly within the city if they knew where it was. And as far as i know Korea is very efficient in keeping track of their underground in Seoul.
