Leslie has said these things about the location of this meeting. It may or may not be helpful.

We might have the Dark Side starting in a place called the Abyss Labyrinth, a large catacomb like area tainted by Nyarlathotep's dark presence. The entrance could be north of the White Woods.

For anyone still confused and in need of clarification: The Abyss Labyrinth is an actual place. It's corrupted by Nyarlathotep's darkness, so it seems like an other-worldly area. Just think of it as a large catacombs. The cult that worships Nyarlathotep has been using it for many centuries.

And yeah there is no might, it is taking place in the abyss labyrinth north of the white woods.
