OT: What does "Inkpot End" mean?

[Chazar]

I know what the site does and I am happy with it game-wise, but I cannot make anything of its very name! What does it mean? Why is it naturally unique? Why does it spread disease and unrest?

For most sites their names give you some idea what they look like and what happens there in a fantasy world, but I cannot imagine anything sensible about this one! Is it there because the godly-map-drawer of the world ran out of ink while drawing/creating the world, and therefore the world ends at this unholy spot (disease, etc.)?

I am not interested in answers from a gamers viewpoint! I want a thematic answers and pointer to other settings where this occurs (google "inkpot end" yield only dom2-related hits!).
