I am the Empty Ekistician.
I am the man searching for Doorways. Searching for the City. Searching for a place without Shadows.
There are records of it (most are false). There are people who have claimed to have seen it (most are liars). There are those obsessed with it (most are like me) and those who wish to exploit it (most are never going to find it).
I've found a total of six Doors. Only the first one has led to the City.
